DnD have very simple engine. But most interesting
If I may suggest... hmm... I couldn't read other posts. U must play:- IcewindDale I & II with all addons- Baldur's Gate (I prefere Icewind Dale, but many people will don't with me)- Star Wolves- NwN 2 with mask of the beastpreyer (czy jakoś tak xD)- Titan Quest- The Wither
It's very, very little % from all fine games, but this is my favorite rpg
