God Eater Burst (D3 Publisher changed the title for the US, supposedly to not offend Christians, to which I say "**** political correctness") is the only new release for me this week. I can't wait to bite chunks out of monsters with my sword to gain new skills, but in English. And in the game.
Calling Dissidia Duodecim Prologus a "downloadable game" is almost as misleading as calling Dissidia a fighting game (it's more like Armored Core with a level system and Final Fantasy characters instead of mechs). It's a cash grab, a paid demo with significantly less content than a lot of the free demos Japanese developers have been releasing lately. On the other hand, it's an exclusive single-player scenario, involving one of the new characters, that sets up for the full game next week; you can carry everything over to the full game, though most PSP demos are like this nowadays; and you unlock Aerith as an assist character in the full game if you have clear data from Prologus on your memory stick. So you can also look at it as being like $3 pre-launch DLC.
Parasite Eve finally being on the US PSN is awesome, especially since word on the street is it'll only be $6 (most Square PSone classics are $10). I'll probably wait until next month to pick it up, though, since I'll have money then.
Also, Jikandia is a PSP game, not PS3.
