I have a bunch of things I'm working on or have worked on. Will I "finish" any of them? Probably not, but they're playable now. I'd love feedback! (Unless it's negative. Then I'll just appreciate it.)
Winner of "Overall Favorite" for the 2011 RPG Solitaire Challenge. It's a solitaire story game - make a little story in an hour or two, and have fun doing it.
Digital: Total Party Kill
A multi-character roguelike. Somewhere between a roguelike and a Fire Emblem-type tactical RPG, inspired by board games like Warhammer Quest and Ravenloft, set in a post-apocalypse but really that's just color. It's fun for an hour or so, if you can figure out how to play it.
Analog: That's Drama
A storytelling card game. Can be used for a one-scene-play that takes twenty minutes or a three-hour epic.
Analog: Blackbird Pie
Because of my frustrations with The Pool and RISUS I hacked Lady Blackbird to make this. I ran it a few times and it's solid. These days, though, if I want to run a generic-setting GM'd RPG I'd probably run In a Wicked Age without the oracles...In a Wicked Age creates more intense, deeper fiction with lots of player-vs-player intrigue, whereas this is better for party-oriented action-adventure.
Analog: My Supernatural Romance
A tabletop RPG / story game for couples that I made to play with my wife. We played it a few times. It needs ... something ... but I don't know what. And I've burned my wife out on story games, so I'll likely never figure it out.
Analog: Nowhere Road
My entry for GameChef 2010 - a "Make Your Own Road Movie" RPG. It's GM-less, and all about epiphanies - the characters think they know what they want but the other players know what the characters really need. It's quite fun, but, jeez, could I have picked a more narrow genre to make a game about?
This uses Once Upon A Time cards with (mostly) the rules for Archipelago II to make a great game for roleplaying with children. Once Upon A Time, played as written, usually generates an incoherent story with lots of random crap happening all the way up to the end; played this way it results in a solid story but plays slower than Once Upon A Time (it can take an hour, hour-and-a-half to play) (but it's faster than Archipelago, which usually takes me multiple sessions.)
Analog: Brik: Tactiks
A super-simple tactical wargame with lots of critical hits that one could play with, oh, just for example, Lego.
