I currently dont have a favorite since I've never had the chance to play any of these titles. Hope I get the chance to truly have a favorite character amongst these titles, I've heard a lot of good things.
I haven't played Neverwinter Nights in ages. I've been partial to a Dwarf Fighter character and remember I had a cool character back in the day. I haven't tried out Disco Elysium, yet, but I hear the characters in that game are epic. Nice giveaway!
