Man, that's kinda a shitty PS3 lineup. Does Japan even care about GoW? And some of that other stuff...the worst Fatal Fury, a LocoRoco game that's more of an interactive screensaver than anything else, Sonic 1 (while still great, it pales in comparison to later Sonic games)...really disappointing lineup.
PS+ in Japan has always been a joke. 98% of all the free games offered since the beginning have been bad PS1 games and all the trial games have been old PSN games. I wouldn't expect much from their IGC.
