Re: Original Fantasy Hero
The Second Edition of Fantasy Hero is best IMO. I loved the Spell Colleges, actually. Spell Colleges (Fire, Ice, Darkness, Church of Purity (eww), etc.) are just specialized colleges of magic. I actually wrote up some Racial Colleges once.
Fantasy Hero Companion I & II are pretty good as well, though some of the art is not that good. Personally, I love the succintness of the second Edition of Fantasy Hero. But the new edition has a lot of useful information.
Personally, I think they should break Fantasy Hero down into two books. Book #1 would be for players and GMs, Book #2 would be for GMs alone. You know a Fantasy Hero sidekick.
