+1 for indie games. I really think we're living in the golden age of indie gaming with tools like Godot, Unreal, and Unity (yes, yes, I know, but Unity is probably still the most popular engine for now). As indies get empowered more and more by tools like this, and AAA studios get greedier and greedier, I can't find any reason to play anything that isn't from an indie game developer.

And most, nearly even all indie games work great on Linux, often even better than their Windows counterparts.
