Space Station 14 [0], which is the remake and spiritual successor to Space Station 13, mentioned elsewhere in the thread.

SS13 is a wonderful game, but it's so old and its codebase is so messy that people have been trying to remake it for years. Attempts had mostly gone nowhere until all of a sudden SS14 took off with a few dozen OSS developers. Now they're making fantastic progress (see [1]) and have a game that isn't just playable, but enjoyable! (Not to mention being almost completely on-par with SS13 at this point, with several distinct maps and hundreds of items ported over.)
