wait, so what happens after you've gotten all ur attributes to 100? it's bound to happen if you go all the way to 255
Normally your character then no longer levels up and you just keep playing. This normally happens around levelish 50 depending on the racial/specialization perks your character started with (that's why it can vary some among characters).
For some reason, some players then go to jail a lot and spend loads of time there. Jail can cause your skills to atrophy and decrease. Then these players build up those skills again and level again. Wash (yawn), rinse (snore) and repeat (zzzzzzzzzzz). End result? You get to fight goblin warlords that have 7,000 hitpoints. If you like duking it out with a goblin for an hour to kill him, go for it I guess. :snoring:
I guess the attraction is a carryover from other games. In most games getting to a really high level is a good thing. Not so in Oblivion.
There is nothing new to see or do in the game that cannot be seen or enjoyed by level 30.
