I just bought the three BioShock games. But I've been too busy cleaning up my apartment to play them yet. I'm not sure what I'll get, but I got them and all their DLC for less than $60. So it was not expensive.
Not a video game but my ATR 2500 Microphone for Let's Plays + OTHER **** came in today. I'm so glad. I haven't tested it out yet; a mic test should be imminent but who knows.
As for video games, I'm considering buying Kid Icarus Uprising. It sounds like a good game.
