So I'm a newb and didn't read the posts about the skill book trick until it was too late and I'd already read them all. (I'm referring to the fact that skill points/trainers max out at 100, but by saving the skill books til the end, you can push every skill up to 120).
I was planning to play well into some expansions... How necessary are 120 skills? Will I still be powerful without them, or should I just start a new game? Or do the expansions increase the limit anyway and make this a moot point?
