Easiest thing to do with Oblivion.....create a custom character and put your primary skills as shit you wouldn't ever use so that way you can max all your other skills and still be only level 1 or 2 by the time you fnish the game.

It's cheap and gimp but it's the best way to get around their retarded creature level up system...I mean fuck, the only reason to level up in RPG's is to be able to outclass your opponents or go back and smack the crap out of creatures/characters that hassled you when you were low level
