Dark Cloud series, Rogue Galaxy, Champions of Norrath Series, DEFINITELY Kingdom Hearts (Although there's a plan of a Kingdom Hearts hd collection... In Japan), Wild ARMs, Resident Evil Outbreak series, .Hack saga, Legend of Legaia 2, Digimon World 4 would be a nice addition, although I think many would disagree. That's all I can think of for now.
Oh! Also need the Tales games that were on the PS2, also Grandia 2 and 3.
Star Ocean: 'Till The End Of Time, Final Fantasy 10, 11, and 12, Wild Arms 3, 4, and 5, and Suikoden 3, 4, and 5.
Pretty please with sugar on top and a bag of potato chips with dip?
I know I've already posted the games I'd personally like to see on PSN. But, I feel that the entire library should be(or eventually be) available for download. I really hope that Sony will eventually make this happen.
