Nope never did that, collection never got big enough to do that. Whats kinda weird is that in some ways I consider the game's platform to be the genre. Like original Xbox is definitely its own set of games compared to GameCube, and Genesis games had their own feel versus Nintendo stuff.
I feel movies and CDs should be categorized by genre though. It seems weird to put a rap CD next to a classical CD. or a Disney movie next to a slasher
