What RPG would you like to see published?
I would absolutely LOVE to see No Rest For The Wicked get some official love from 2K Games -- it's a note-perfect build for a videogame-to-tabletop translation. And I'm not just saying that because I helped to playtest the game.
I'd love to see a Fallout-branded game of some sort; I think Apocalypse World is great but I feel it's probably too dark and serious for Fallout. The Fallout series needs both a humourous, gonzoish twist and a willingness to buy into the alternate history of the universe that AW doesn't have right out of the box. That said, AW 2nd Edition is AMAZING and you should buy it now.
I'd be brilliantly happy if someone wanted to help me work up some rulesets to fit around my "Secret History of the Intelligence Services" idea that I tried to flesh out a couple of years ago, I would be really interested in that -- I'm terrible at mechanics but I collaborate well -- but I would fall over my own feet rushing to my wallet to buy a game that was based on the life and times of Mademoiselle Maupin.
How about y'all?
