After I finish Baldur's and Icewind, I will definitely play The Temple of Elemental Evil (not Arcanum, nor Neverwinter). TEE did something interesting. Only game ever based on 3.5 D&D Rules, and it kept the background as sprites but the characters and creatures were in polygons and looked good. I remember long ago their style with the circle selector to choose a function.

I don't think I am interested in Shadowrun and Wasteland. It seems to me RPGs are confined to the medieval period. More fun and interesting that way.

Next is obvious, play Torment 1 then Torment 2. Next I believe is Tyranny. Then Pillars of Eternity 1 & 2. Next is Divinity Original Sin 1 & 2. And last but not least Pathfinder Kingmaker.

Am I missing anything?
