I was playing Rise of the Tomb Raider pretty much non-stop, a lot of fun. Gorgeous game and runs really well on my potato but...hehe Epic Games did something and now ROTR along with a lot of other games just appear as "OS Unsupported" in my library :) and after a little searching on the other site turns out everyone is having the same issue.
Oh well, atleast Epic Games gave away DRM free versions of those games so I can still play my copy
