I return! Here's my ruleset for Index Card D&D - a collaborative GM-less super simplified dungeon crawl game. Basically, everyone spends like 15 minutes creating a class, monster, treasure, room, and trap, and then we play a simplified D&D with the results. It's silly fun and always unbalanced, and you accumulate more cards the more you play. We've super been enjoying it, so I figured I'd share the current iteration of the rules. It's especially fun with a beer in hand!

If you play this, I'd love to hear about it! Feedback welcome, especially if the directions are unclear. I'm thiiiinking of running this Friday or Saturday night at North Texas RPG Con, since there's a dearth of games in those slots (and it was fun trying it last year), so hit me up if that's something you'd be interested in. :)
