JudasIscariot: Do you or your brother like RPGs? I know of several indie RPGs if you are interested.
Detlik: Yeah, he does :) give me your tips please
Well www.spiderwebsoftware.com has tons of them. I prefer the Geneforge series myself. Lots of demos that are quite long so he would definitely get a feel for the games.
Eschalon Book 1 and 2 from Basilisk Games. Crisp clean graphics with an easy-to-use interface. The game plays sort of like a roguelike in that if you don't move the enemies don't move either. Make your class how you wish. Isometric view.
Knights of the Chalice. See my "Knights of the Chalice Appreciation Station" thread on these forums for a good description of the game. Made by Heroic Fantasy Games.
