I really wanted to like FF8 but it's characters bothered me alot. Also the whole draw magic and store it was FLAWED LIKE CRAZY. Great I got spells but I can't use them?!!? Awesome!
I'll admit FF7 had it's bad moments too but on the whole it was a much better game.
FF9 wasn't bad, I actually cared what happened to those characters.
Even though I ended up hating it FF8 was waaaaay better than X-2, they should be ashamed of that one.
So yeah, out of those listed I voted FF7 because at the time it was Epic.
