I'm lvl 50, and i think it's svcks have to play the game again by the 5st time to play as a mage...

There is a way to level to infinites levels and get all perks? (mods and stuff)

I never will get why people hate having more than one character.

And no, there's a level limit. I think it's around 81 or so.

yes level 81 is the cap and you have to master every skill to get there but by the time you get to 50 your char will be powerful enough.

If on PC, you can get to 81, then use the console to give yourself all the remaining perks.

Personally, I hate redoing things ive already done. I already know what happens, so why would I think it will be more enjoyable a second time around? Plus I am not the kind of person to do different playstyles. I play the way I want and thats it. So I like to do everything on one character.

The reason there is a level limit is because the skills max at 100. There is probably a way around that. I wouldn't know though.

I can see why people would like to have one character, perhaps they become attached to them?
I can also understand the reasoning behind multiple characters. But with most TES games anything that strays to far from either architype ends in disaster - unless you like running away from everything.

The answer the OP is looking for is this:

Yea That how I play I mostly have one or two characters and really don't do different playstyles eother.

Can't you also add perks via the console?

yes

player.addperk

I think that's it. Something like that. You will have to look up the codes though.

Dunno if you can get more than 80 perks that way. Something to look into.
