So I'm a first time DM and it may sound ambitious but I'd like to create and run a 5e game set in Sigil. I know the Planescape sourcebooks are for an earlier edition of the rules, but strictly for the lore and setting, would I need the whole box set, or would "In the Cage" give me enough material to work with?
In the Cage is a great resource. I'm running a Planescape campaign using 5e rules right now, but I have the benefit of the original sourcebooks from the 90s that I've held onto for all this time. Strictly speaking, Sigil is just like any large city, and you can port a lot of pre-existing city adventures into it (just change some of the races and really describe the peculiar nature of the Cage) but to get the full experience, the other two sourcebooks I'd recommend (both available on DriveThruRPG, if I'm not mistaken) are the Factol's Manifesto and Uncaged: Faces of Sigil. Between those three, you'd have a wealth of material to work from, and the Factol's Manifesto is really key if you're going to have planar characters who are members of factions. Another favorite of mine was the Planewalker's Handbook. Very useful from a character's perspective. Hope that helps!

Thank you, Gorthmorg!
