What do y'all think of having 2 or more DMs?

Starting to do co-dming for my players, what do y'all think about multiple DMs?

Depends on how well you know the other person. The better you know them, the more likely you are to know what they’re thinking and be able to help them out. If you aren’t coordinated, though, it can be a muddled mess.

I'm getting ready for a PvP campaign that'll actually involve three DMs. like link said, it'll take coordination to pull off properly. However, though it may be tricky, having an extra brain helping worldbuild and design can be totally worth it!

It’s true that it will give you more ideas and design between all of you… if you can pull it off. Otherwise, it can become a muddled mess.

Write a very rough plan for the story so that everyone knows what to run ish

rough that players have agency 

Do you plan on having each dm running both story and the technical side or are you splitting the responsibilities? If the later, I think it could definitely work. I saw a dnd staged production called "The 20-Sided Tavern" where they had one dm running the story and one handling the rules and numbers and that system worked well for them. If you share the story, you really just need to make sure you have the same vision. With both styles cooperation and trusting your co-dm is vital.

Hey I saw that too!

it was pretty funny. The crowd named the villian npc munglebottom.

I think you'll need to have a firm division of labor in play -- for instance, one person runs the world, while the other plays individual NPCs. You'll also need to be able to have a side-channel for talking to each other -- texting on your phones, for instance, with occasional stepping into the other room to confer. (It doesn't matter how much you prep; the players are going to throw you curveballs.)

Prep is likely going to be the hard part. Unless you both have compatible styles, it's going to be a fair bit of work to stay on the same page. For instance, I'm very much a seat-of-the-pants GM. I do minimal prep, and keep most everything in various stages of incompleteness in my head. To work with a more meticulous GM, we'd both have to adapt. I suspect that, among other things, we'd have to do immediate post-session debrief, where, were I the lead GM in play, they'd have to ask me what I was thinking about various improvisations during play, and get them down in fixed form before I get too fuzzy on the details, so they're prepared when an entire major campaign plot arc appears out of basically nowhere.

Edit: I suspect that, like co-authoring a book, it's a lot more work than doing it solo.

I’d talk about how you will handle DM ruling situations. Maybe do something like whoever is DM’ing makes an on-the-fly ruling, but then both of you confer after and inform the table of what it will be going forward. You just need to make sure that rules aren’t going to change on the players from one session to the next.
