You can still try playing them using Steam Proton.So I completed Life is Strange: Before the storm few days back.
I have almost left playing games and use Linux now exclusively. I intend to complete some games in coming days. Especially following:
Quantum Break (left it after playing half)
Half Life (yes, that's still incomplete)
Bioshock (damn it was a good game that I also left after playing for a few days)
Mirror's Edge 2: I think it's been more than a year since I purchased the game, and still haven't played it!
