What books are best avoided in the Rifts line? I know at least South America 2 is probably on this list. I don't like the players being super-powerful, and some of the books put them on the level of taking on gods.
Stuff I currently have:
Rifts anniversary edition
Sourcebook I: Archie
Lone Star (mainly for the dog boys)
Mystic Russia (haven't delved too deeply into this. Are there any ridiculous PC races/classes?)
Books I know I want:
I used to have a bunch of Rifts stuff, but sold it off. I regret it now. Most of the games I've gotten rid of are in better hands, but I still love the idea of this game, if not all of its implementation.
