My Playstation (one) games
Oh look, it's a list of jRPGs, with one or two non RPGs thrown in for good measure.
This list once contained a lot of other genres, such as 2D fighting games, more racing games, a couple of Tony Hawks, and some other oddities. Most of those games have been obsoleted - to be fair, many of the games still here are also available via PSN (at least 17 of the 24). A couple of them I've bought on PSN, despite already having the original disc. Some, I've never played, and some I may never play again. However, I don't intend on getting rid of this core any time soon. Except maybe Suikoden and Suikoden 2, if the US PSN ever gets Suikoden 2. Which it won't. :(
Edit: OMG IT DID!
