I loved the Baldurs Gate games, still have them and am giving Shadows of Amn a replay at the moment. You can buy both games plus the expansion packs in one box now.
Being complicated is the point for me. I utterly hate the lack of choices in modern RPGs. I don't even know why they call it an RPG. WoW? joke. MassEffect? joke. Space siege? ... wait, why did I even try that?!!
Thats the one I got, the only reason I bought it was because of the awesomeness of Baulders Gate 1+2 on the PS2. Many a happy co-op session spent instead of going to college! My issue with the D+D games is that they are so $%*^&ing complicated! Srsly, anything more then like 10 commands and I start going cross-eyed!
