for me id love jet set radio and oddworld strangers wrath
Definitely agree on Oddworld, although I think they should re-release all of the OW games. Grimm Fandango would be nice too, as I've never had the chance to play it.
Although I doubt it would happen, an HD re-release of the Kingdom Hearts games on XBLA would be awesome.
Castlevania: Symphony of the Night, Chrono Cross, Chrono Trigger, Final Fantasy VII, Metal Gear Solid, Xenogears, God Hand, Odin Sphere, God of War, God of War II, Sly Cooper, Sly 2, Sly 3.
Oh, wait, I must be trolling, because these are obviously already available on PSN.
@spyder335: As they are bringing a HD version of Oddworld Strangers Wrath to PSN maybe they will port it over, there are some rumours indicating this but no confirmation yet:
@shootermcclay: Symphony of the Night is up on XBLA. And XBLA titles typically mean the games are improved or enhanced in some way, not straight up emulations like those PSOne titles are - which in my opinion, is an utter waste of time, none of those games are that old are hard to come by.
My vote goes to San Francisco Rush 2049.
Add in online play for multiplayer (16 players on stunt tracks, 4-8 for races) and a light graphics overhaul and this game would be hella fun.
Already mentioned in this thread but definitely needed:
Chu Chu Rocket
Jet Grind (Set) Radio
Pac Man Vs
Conker's Bad Fur Day (just original multiplayer w/online would be sweet)
