So I just joined a new campaign with my sister. There is me , her + two others in the party and we have such a strange set of characters, we've only done one game so far but I can't wait to see how our characters react to situations all being so different.

Our DM allows all alignments excluding neutral evil and chaotic evil. But we've got me who is a neutral Arakocra (vulture) who's a loyal duellist/bard. My sister is a lawful neutral nymph/satyr who's a ranger, the other two are a not-so-smart neutral hobgoblin sorcerer and a chaotic neutral Yuan-Ti pureblood sorcerer who so far tries to cause the most chaos while my sisters shy/kind satyr has to watch in horror. XD
We're all still getting used to how we'll play our characters but I can't wait to see how it all plays out.

I run a game for a group of ladies who wanted to all play D&D as anime-style magical girls. In the end I helped them all make a party of Warlocks.

• Hexblade Warlock - the "Fighter"
• Celestial Pact Warlock - the "Cleric"
• Fey Pact Warlock - the "Rogue"
• Fiend Pact Warlock - the "Wizard"
• Great Old One Pact Warlock - the "Bard"

All in all, they have a fun time of it.

My daughter's D&D crew which I DM is unusual with the following:

The Halfling monk who runs away about half of the time they fight.

The Warforged Eldritch Knight who rarely melees

The Barbarian who uses his bow more than melees.

The Thief Rogue who never does anything sneaky.

The Onomancer who shield (the spell) tanks more than anyone else....

No healing until just this past week when the Onomancer took a level of Artificer.

I technically have three parties right now. An actual campaign, a one shot to help some new people learn dnd, and a one shot I am dming with some family.

Campaign:
Half-elf Ranger with kleptomania apparently
Half-elf Cleric with people problems
Half-elf Rogue that I keep forgetting is even in the party
Kenku Rogue that doesn't speak common and rarely rolls above a ten
Dwarf Barbarian who never uses rage for some reason and keeps trying to sex everything (I think he is really just a terrible bard)
Warforged fighter with horrible charisma that almost always nat 20s charisma rolls and is kind of the leader but doesn't realize it

One shot with new people:
Red Dragonborn Barbarian with 4 int and a magic greataxe
Half-Elf Ranger who only appears when its his turn
Dragonborn druid who keeps picking up twigs
Fire Genasi Wizard who thinks we're all idiots (we are)

One shot I am DMing:
Dwarf Cleric who is literally just Guy Fieri in dnd
Half-Orc Monk with horrible rolls
Tiefling Ranger who doesnt get to play a lot cause of work
Goblin Bard that plays the bagpipes and somehow became a mob boss

I'm loving them all so far, they sound like such interesting parties haha.

Here is the party for my current campaign I am DMing.

Veldakan Battle Smith Artificer
Hill Dwarf Forge Cleric
Changeling Way of the Open Hand Monk
Blue Dragonborn Eldritch Knight Fighter
Winged Tiefling Bladesinger Wizard

I've had two one time players that joined up for a session or two at one point with a Minotaur Circle of the Moon Druid and a Tiefling The Great Old One Warlock.

My previous campaign had the following party.

Tiefling Bard
Wood Elf Circle of the Moon Druid
Wood Elf Assassin Rogue
Goliath Champion Fighter
Human Beast Master Ranger / Celestial Warlock

Interesting choices from my players but they are happy with them so can't complain!

I've filled in NPCs as needed for certain things.  I have a Gnome Phoenix Sorcerer and a Human Lore Mastery Wizard.

So, in my current campaign we didn't have a session zero or share information about our characters before starting... as a result we started the game with three rogues... An Assassin, a Swashbuckler, and an Inquisitive... eventually the Swashbuckler left the party due to scheduling conflicts, but we ended up in a situation where we had to travel extensively with an NPC who was a Rogue Thief. Other than that the group is a way of shadow monk, college of lore bard, and a homebrew fighter focused on tanking.

Oh gosh, I can see how chaotic that could get haha, yeah we don't do session zeros yet because thankfully my groups we just send out sheets to the DM (or when I'm DM) they send me theirs and if we see issues with class composition we talk it out in Discord or Facebook. 

But yeah having that many stealth based/DEX builds would be hard to balance out. 

Currently...

An Enchanter Wizard who is a pacifist...making him more like a bard.

A Light Cleric who favors blasting over healing...making him more like a wizard.

A Swashbuckler Rogue who drinks constantly, sings songs and tells stories...making him more like a bard.

A Devotion Paladin who recently has taken to using a crossbow...like a Fighter.

And a Sword Bard who...actually seems like a bard.

...truly, we seem to defy the parameters of our roles.

 Oh yeah, the fighter is the only person in the party with a STR above 12. If she ever rolls bad on a strength check then the rest of us have to like... build a pulley or something to even attempt whatever she was trying to move.

A ogre, who is pacifist fighter, using only a shield. 

A chain smoking, one armed goblin, mastermind rogue

A path of the Ancestral guardian barbarian bugbear, who loves puppies. 

And a droopy eared goblin conjurer wizard, who praises my brother's human fighter noble like a god, despite already knowing that he isn't a god. 

In my sunday game we have...

A changeling Great Old One Warlock who is also a werewolf.

A Levistus Tiefling Storm Sorceror who is naive as hell.

A Goliath Fighter/Barbarian with the Headband of Intellect who is a crit monster

A Warforged Artificer with a cyborg cat.

Note that we are in a Forgotten Realms themed campaign. Some of our special followers include a young brass dragon who likes to talk about the desert, a stone giant and two former members of an Orcus Cult, one of which is the warlock's brother and also undead, and another is a super buff Goliath lady named Ivana Krashu.

A slightly less odd group was the "Zoo Crew", so named because it had a Dragonborn, Kenku a Tabaxi in it (plus a human and dwarf). The class composition was two rogues (Inquisitive and Swashbuckler), a Hexblade Warlock (who played like a rogue) , an Order Cleric and an Artificer. We were doing Waterdeep: Dragonheist, which was sort of the reason I think for the heavy rogue focus.

The campaign I'm in has:

half-elven College of Lore Bard - with very low INT, but ofc high Charisma, she got seduced by a red dragon, not the other way around
half-orc Storm Herald Barbarian - who is somehow the smartest of us
dwarven Light Domain Cleric - who has a very fashionable beard and a shiny armor
wood-elven Circle of the Land Druid (me) - he's very childish, also I love using the Primal Savagery cantrip, therefor sometimes called a "Feral Child" xDD
and a DM controlled Imp who's so done with us xD

The Bard, Cleric and I hug/shoulder pat/high five our Barbarian everytime we cast a buff on him xD

My current campaign (Eberron setting)
Me: Warforged Artificer. Firearms proficiency (carries a 4 shot revolver), dresses in a duster and widebrimmed hat to seem less obvious in crowds. Is still six foot eight and has golden scale mail armour, so good luck with that. Has a four eyed mechanical German Shepherd, which will become a Steel Defender once I get to level 3.
PC1: Warforged Druid. Has stripped away all metal parts, wood armour, has subconscious original programming but mostly is unaware of it's existence.
PC2: Warforged Paladin. Bouncer, god of luck, 18 Charisma. Normally I play the paladin, so interesting to see it from an external view point.
PC3: Elven Rogue. Pretends he's a bard, but has a ridiculously high Performance skill, so it's a good deception tactic. Carries a scimitar, hopes to get a second.
PC4: Half-Elf Bard. Is determined to make a story out of everything, and in our one combat we've had so far spent the entire combat Viciously Mocking everything.

Mix and match of vets and newbies:

artifcer protector

bronze Dragonborn Draconic sorcerer 

sea elf religious zealot Druid

changeling Rogue

little more “hardcore” of a campaign where you have to do stuff to get the level ups.

always an interesting and fun time when you have no “true tank”

I am a DM (first time!) for a 3-player party with interesting overlap and gap in skills;

- A Half-elf Rogue (Scout)

- A Tiefling Bloodhunter (Lycantrophy)

- A Wood-elf Ranger (Archetype to be determined)

They all have similarities in skills, similarities in flaws, yet each also has something which makes them unique in function from the others, so it's quite an interesting dynamic! (The Bloodhunter functions as a tank, the Rogue serves as the skill/proficiency monkey, and the Ranger serves as the ranged fighter. Also both the Bloodhunter and Ranger have some small amounts of spells as per their race or class)

My current players are:

Chaotic Good Goliath Wild Magic Barbarian 7 / Wild Magic Sorcerer 1, who is imbued with part of the wild magic spirit of a dead angel. His goliath markings disappeared and he's covered with constantly moving writing that tells the future, but he is the 'Fate Breaker' and is immune to prophecy. 

Lawful Neutral Half-elf Order of the Profane Bood Hunter 8 (about to take a level in Wizard), who went a very dark path serving a Great Old One until the G.O.O. tried to betray the party. He refused his patron, and made a new pact with the dead wild magic angel who infuses the barbarian, and now bleeds rainbows.

Lawful Good Hill Dwarf Tempest Cleric 8, who is the living embodiment of a sentient god-storm but doesn't know it. He is the most compassionate and caring of the characters, and falls to being their leader through his moral compass. 

Chaotic Neutral Half-Elf Swashbuckler Rogue 5, Battlemaster Fighter 3, who is in possession of a book that teaches fencing techniques (me and the other players have all trained historic swordsmanship for years). The book is in fact a demon that contains the souls of all its previous, consumed owners, and is slowly devouring him. He is the Face of the party, but a bit clueless.

My current party is an orc artificer who's obsessed with gaining strength and power to prove his worth to his tribe, a friendly ooze who the artificer found (uses ooze cohort rules and class) with con 20 so has oodles of HP, weird to have a small-sized tank! We have a half sun-elf monk who's going to be multiclassing to draconic sorcerer, a drow druid who has recently discovered that her father, who she thought was imprisoned for all these years, escaped forever ago and left her notes in their favourite place (which she never went back to until the start of the campaign) telling her to come and find him. The notes were over a hundred years old. We have also got a wizard who was a good enough magician to trick himself into a mages guild, and now studies chronurgy, and enjoys using the catapult spell to destroy things like skeletons!

They're an odd sort of party, but they are working pretty well together so far!

In the main game I am playing, we are all 4th level:

• Human Battle Master Fighter,  Neutral Good, that's my character.
• Half-Elf Hunter Ranger, I think she's Chaotic Good.
• Gnome Wizard, He's Chaotic Lawful, he rarely casts spells, and prefers to fight in melee with a great big sledgehammer, but when asked nicely, he'll usually go along with it.
• Lightfoot Halfling Rogue, she's an Arcane Trickster who never uses her Mage Hand, and plays like an Assassin most of the time, she's another Chaotic Lawful.
• NPC Water Gensai Druid, she's a character the DM plays in other games, and she's probably Neutral Good.

In another game I am playing, we are all level 2nd Level, and there are a lot of us:

• Half-Elf Warlock of the Fiend, she's Neutral Good, that's my character.  (I'm not all that good at playing any other Alignment)
• Dwarf Barbarian, no idea what Alignment yet, but that's the same one as our Rogue in the other game, and he's over 6 feet tall.
• Changeling Bard, no idea what Alignment again, but that's our DM from the other game.
• Lightfoot Halfling Rogue, she's a Thief with Expertise in Deception who lies to everyone and steals anything not nailed down.
• Fairy Cleric of the Life domain, that's our Gnome Wizard, and the character is about 2 feet tall.
• White Dragonborn Paladin, he's probably Lawful Good.

I'd call it "interesting" at the very least.  Thanks for making the post.

Current campaign I'm in has three playera:

I'm playing a young female Goliath Genie (Marid) Warlock, who has a sense of justice, and is the heart/Moral Compass of the group. As well as the youngest and tallest. 

A female changeling bard, choatic neutral but genuinely a good person, and will probably become the leader of our group.

And finally a nonbinary Air Genasi rogue, who is in service to asmadeus. Though unaligned, he's technically neutral/chaotic evil, but due to the mark placed on his right hand; he's unable to harm anyone who is not evil aligned.
