I remember playing the Geneforge games back when I was younger and they hold a lot of nostalgia value for me, as well as just being overall fun and an experience. They are definitely my favorite of Jeff's games.
I'd like to play through them all again starting with the first game, and I was curious what classes are the hardest to play in each of the games. I'll be playing on Torment as it gives me something to work towards achieving.
