If I beat the final boss on easy while I played it on medium throughout the game, will it change the ending? Just wanted to know if the game ends differently depending on wether you beat it on easy or medium.

Oh and at the final boss, it's animation makes the game so laggy that I can't play it. I think I am forced to beat it on lowest graphical setting. :/

I haven't tried different difficulties, but I'm going to assume no, since there's no real "ending" as I suspect you are imagining it. It's not a bunch of posterboards or cutscenes explaining what happened and who went off to marry who or anything like.

It's more like the different endings pertain to the different circumstances you find yourself and the world and major characters in at the end, which you experience as you play through to the end....if that makes any sense. :p

Thanks. I might want to beat the final boss on easy. It's a real tough cookie. =x

But then again I beat the rest of the game on medium. >_>

Just do what i do, attempt the last boss on normal difficulty until you are too frustrated, and then turn it down if you need to.
