Yeah, I meant the average player. Not necessarily the average gamer, but the average FF player.
When I played FFVIII, for instance, I got all the way to Adel before I died, and I wasn't trying to level whore then. In IX, I actually managed to get through the whole game without dying, and I wasn't even using a strategy guide. Had some definite close calls, but never actually got that game over screen without trying to.
In X, same deal. Had some close calls, but never actually kicked the bucket without trying to.
I know I got game over in the earlier FFs before reaching the end, as well as in VII (it was my first FF) and XII (could be pretty damn hard at times), but not anything on the order of how many times you'll die in XIII.
