I'm wanting the game to be actually hard, so I won't have an overly easy time beating the final boss. Yeah, there should still be an "extra" boss that is harder, but I don't want the final boss to be super easy, either.

I think there should be more plot twists the X had. There just wasn't enough that was unexpected (which is very little). I want more things that make me drop the controller and let my chin hit the floor. I want to not know what's happening and have to figure it out later. I want to have to speculate as to what the hell is going on, rather than just knowing.

Basically, make it a TRUE FF game, nothing like X that's too easy or VIII which was far too different. (By the way, I enjoyed both games. In fact, I love them! They just weren't FF games...)

Oh yeah, and there should also be a really, REALLY cool final summon that you can get that is overtly powerful, but nearly impossible to get if you don't know what you're doing (ala FFVII).
