It struck me that I've never seen this question asked anywhere, so thought it would be interesting to find out.

Planet Coaster and A Hat in Time!

Torment: Tides of Numenera is my most anticipated. Planescape: Torment is one of my favorite games of all time, and I have big expectations for its spiritual successor. 

Besides that System Shock 3 and Star Citizen of course. 

System Shock 3.

I thought that was coming to xbox? Or is that system shock remastered or a totally different game?

Hearthstone: Whisper of the Old Gods. The meta game is stale right now. 

I ll 2nd that.

I have high hopes for the new Torment game.

Hmm, never occurred to me when I look at my pc to get an exclusive game for it, I just buy a game that my PC can handle, or play MMO's on it, weird. On topic, even though it's not an exclusive, I'm looking forward for Dark Souls 3 just because it's cheaper than the PS4.

Half Life 3.

Ghost Song.
