Baldur's Gate 25
Baldur's Gate II 25
Eye of the Beholder Series 14
Icewind Dale 7--because it's full of tedious thinly veiled excuses to kill hundreds of monsters that are just minding their own business, and then at the end of dragon's eye they try to gut punch the player that it was all for nothing and there's a bigger danger on the horizon. I knew it was all for nothing Icewind Dale, you told me that repeatedly in the quest text /rant.
Neverwinter Nights 16
Neverwinter Nights II 20
Planescape: Torment 5--because it might be the greatest game of all time, and it deserves to be eliminated at least slightly after Icewind Dale.
