Want to playtest a story game? This is the night for you (the third Tuesday of each month to be exact). Bring a game you want to playtest or just bring yourself to play other people's games.
The cardinal rule is that if you bring a game, do your best to make sure it's something you'll be happy to sit down and play. The goal is to playtest, not redesign games on the fly. For answers to other exciting questions like "how do I know my game is ready?" and "will my game get played?" see the playtesting discussion thread.
Warning: Games you playtest may have unforeseen yet fatal, fun-crushing flaws. Hopefully they'll be awesome, but heck, it's playtesting. Satisfaction not guaranteed.
