I simply can't play a game I'm familiar with, if I know that this file is a much worse version of a previous one.
I restarted FF8 a few days ago, and I really was eager to get into the really fun moments as fast as possible (after all, the first five hours make you fall asleep, damn it :rolleyes2), and doing this, I missed lots of stuff that I usually get.
For example, I learnt the "wrong" Abilties; I usually get Card and the X Bonus Abilities right away, but this time I was just going like "nah, ain't got the patience, I WILL PROCEED NOW!".
Suddenly, I found myself thinking "what the hell? I usually have all of those last elemental tiers and Death at this moment!"
Then I got fed up with the file and restarted the whole thing, playing much more strategically and even took full advantage of the Mid Mag-RF Ability (you know what I mean about "full advantage" ) before even heading for Timber.

This occurs for all FF games, and usually some other games as well:
I simply can't play a game if I feel heavily "inferior" to another, earlier file; it kinda feels hopeless.
