uh... i've heard "it looks like Ehrgiez" from a few places, but i dunno. seems nowhere near it to me... and it WAS a great game.
this game doesn't really seem very interesting to me right now. i've lost quite a bit of interest in FF now that it seems all too repetitive. bringing up a fighting game doesn't seem like it's going to help much. all i can see in this game is any FF main hero vs any FF main villian. to me, that's as much fun as putting them in a poll. i bet most people think "Cloud vs Sephiroth" immediately. (you know, now polling sounds like more fun than this game.)
in the Compilation? don't think so. this is based on FF. not all or mostly about 7. (and to be honest, i'm kind of getting sick of FF7.)
PSP seems like a smart choice. although, it shouldn't be limited to PSP only. it'd be great if they put it on at least the PS2. i have nothing against it being for only PSP though. it can handle graphics, button layout is not different than PS2(*coughlackofsecondnubsuxthoughcough*), and there's a chance of multiplayer for Dissidia, and the PSP is good for that. not to mention you'd be able to have jur favorite FF characters fighting on-the-go.
oh, and one last thing. the main reason i'd play this game... is to get payback on Sephiroth with Aerith.(if she's in the game.)
