I’m likely forgetting a game or two that was played at a Con or as a one-shot (I can’t find any list of what I played at Gencon and Forge Midwest).
Apocalypse World: Got to play for the first time at Walking Eye Con, at Gencon, and Abram’s game. Finished up the Waterworld campaign at the start of the year, and started a campaign (still running) at the end of the year. A good year for Apocalypse World!
Beacon of Hope: Played a playtest session of this, ran by Shari.
Burning Empires: Played in Sabe’s Game Turbine Malvernus game.
Danger Patrol: Shari ran this at Walking Eye Con.
Dogs in the Vineyard: Ran a game of this for Tim, Shari, Sabe, and Misha.
Dragons at Dawn Hack: Ran a short game for the Game Turbine, and a session at Chicago Games Day.
Dungeon Crawl Classics: Played in a few sessions ran by Doc. Ran a few sessions for the Game Turbine.
Dungeons & Dragons, 4th Edition: Currently running my Godstorm game. Played in Sabe’s Hallowdwell campaign. Ran a girls-only Dungeons & Dragons & Disney game.
Dungeon World: Kevin ran a game at Walking Eye Con. Played in a game at Gencon. Currently playing in a game run by Sabe.
Durance: Played this as a one-shot with the Game Turbiners.

Lady Blackbird: Ran this at Plattecon.
Left Coast: Ron facilitated this for me at Forge Midwest.
Legends of the Wulin: Did character creation for a Game Turbine game started by Sabe. I’m still going to count this one, since it’s just getting going.
Marvel Heroic Roleplaying: Ran a few sessions.
Mispent Youth: Played a session of this at Chicago Games Day!
Monsterhearts: Ran a game for the Game Turbine. Also one shot at Walking Eye Con, Chicago Games Day, and for Mik and Kai at New Years.

One Last Night: Played a session of this with Tim, Brendan, and Sabe.
Samurai World: Brennan Taylor ran a Day of Thunder Samurai World game at Gencon, which was completely awesome. I played Mirumoto Hitomi and ended up Empress.
Savage Worlds: Ran two different sessions at two different Chicago Games Days.
Shelter in Place: I played this at Walking Eye Con. It probably doesn’t really count as an RPG, but I played it
Stars Without Number: Played in a few sessions ran by Doc.
Unnamed Casino Game Continuing Playtest: Continued to play. Abram ran a session, and it went well.
Edit: Thanks to Tim for pointing out Dogs in the Vineyard and Durance. And The Final Girl.
