Also more info, when I got Oblivion for PC in 2006, I played a full run without cheating or mods. When I got to level 51 or 52, my attribute was under 100 except for personality.
No more level ups. After that I understood leveling, I don't remember from Morrowind, well after my full run on OB, made my own plug-ins for OB. I wouldn't even call it a mod.
It was really a boost plug-in, carry more thing, custom spell (teleport) to the Frost-crag, A book that gained skills. Played OB off and on, now I also got it for PS3, when I finish that I will go back on PC and put some mods.
Just want to give my thanks to those who make Mods for those who can't, and also for you guy spending your time on them.
