Good idea having them in categories, I used yours if you don't mind I just reformated them and merged things into them. I added prices when I knew/thought I knew them off the top of my head. I'm not including current discounts.
I'm only including games that a Vita can get on it's own. Sony's Handheld needs to stand on it's own, not be dependent on it's bigger cousin . (Of course you are welcome to add such games but I won't put them in the top of the thread as there are quite a few people w/o ps3s (me included) and if they work that way then sony needs to move them to the PS Vita psp store if it wants us to reccomend it to our friends etc.
152 PS3 games - 564 PS2 games - 72 PS1 games - 202 PSP games - 11 PS Vita games
Over 1,100 games total
The good news is Sony is finally starting to fork over some games. Though it's still to slow for my tastes 3+ very well recieved games in two weeks is not bad. Now we need the last gta game, the MGS games, the star oceans, VC2, Crisis Cre and we'll have most of the PSP's best games.
Right now all of the Atlus Playstation games are 50% (for another week). So you can get Persona 3 Portable for $9.99.
Just thought I'd mention it. Otherwise nice job OP.
