See, I hear people complaining all the time about how easy FFX was, but I've been through hell with this game, whereas FFVII gave me virtually no trouble at all. I beat Jenova(?) and Sephiroth on the first try, and just stared at the credits going, "That's it?". In the case of FFX, I gave up on the game completely for serveral months the last time I reached Sin's face (before my mom accidentally wiped that file off the memory card).

This could be blamed on the fact that I royally screwed up the Sphere Grid early on because I didn't take the time to understand how to use it, but if it weren't for the three secret aeons and Bahamut, I'd never be where I am now in the game (Sin's Sea of Sorrow). If I tried to level up my players to the point of doing 99,999 damage, it'd take way more time than it'd be worth.

If you do that much levelling up, of course the game is going to be easy.
