Old PC and 360 games. I have no clue what Steins;Gate is, but it was cheap, recommended, and a good way to flesh out my 360 collection.
N64 and GBA games are obscured, but I have 12 and 9 of them respectively. Overall, not the largest collection out there, but I've cultivated it such that every one has value to me. Minus the newest ones, I've played through them all, and wouldn't sell any of them.
