I use Depressurizer to sort everything into store tags.

By genre and if its a big franchise, by franchise like Star Wars.

What about different art styles?

Different major games are the representation of various retrofuturism styles, every one of them reinterpreting the future through another historical era’s vision.

BioShock is a Decopunk game, where the art of luxury and decay is shown through its underwater utopia, Rapture.

Fallout is an example of Atompunk, portraying the post-war Atomic Age in a kind of a paranoid and optimistic way, with its once flourishing and now ruined nuclear future of the 1950s.

On the other hand, Wolfenstein is a Dieselpunk game depicting a world of WWII where heavy machinery, oil, and totalitarian aesthetics reign.

Dishonored looks to Steampunk for inspiration, letting Victorian industrial aesthetics and mystical technology of oppressive empire coexist.

I sort by my library by most recently played and my installed games by size on disk.
