I'm in the same boat. The last AAA titles I played on Linux were Deus Ex: Mankind Divided and Alien Isolation - high end, graphics intensive games. I've been meaning to get around to Hitman - I downloaded the demo a few weeks back and it seems to run fine but not had time to get started with it properly.

I also enjoyed Thimbleweed Park and I see the (excellent, btw) Wonderboy remake was released for Linux this week. Us Linux gamers are incredibly well catered for these days!
