Kingdom Hearts

Yes, and I have the strategy guide too.. and God the minimum lvl you should be for fighting Sephiroth, is 70 and as Medieval Bob said, its fucking hard even if you are lvl 100... but who knows, you might be lucky and beat his ass while lvl 50?O.o
Keep trying Bob, and if it doesn't work, well, then try other worlds that is easier than the coliseum first. So that you can gain some EXP. Fuck the voice, I never even hear the voices of any characters in the game(because I don't put the volume that high, and ppl talk in my family making it hard to hear wutever is coming out of the fucking game. Yes, my PS2 is out in the living room.), so I think the game is really good.
