Steam Library Categories

Is it weird to just leave your library on Recent and then if a game leaves the top 10 just forgetting about it forever?

Favourites (also acts as a "currently playing" when I am playing a longer game)
Action
Adventure (point 'n' clicks)
GTA
Hidden Object
Other
Platformer
Puzzle
RPG (only cRPGs, others are in Action)
RTS
Serious Sam
Unplayed

I had like 30 categories, but then I realised since I only replay a few games, it doesn't really matter apart from a simple classification.

By release date year

Don't judge me!

I don't like to use genre categories 'cause, well, I already know what category it is just saying the name. Actually I didn't use it, but recently I started to clean my backlog and decided to use this: 100% - Perfect Games; Finished; Installed, Uninstalled and Multiplayer

But you can take a look in Steam Store and see some others genres to use for those games :D

Installed - Not Installed. XD

• Favourites
• Rest
• Hidden from library

I have 4 Categories:
Completed
Multiplayer
Everything I still need to play
Fuck These Game

I tried organizing with better groups, but there is so much overlap in a lot of games and they fall into more than 1 category, so I stopped trying.

My system is very simple:

Brand New (at the top, for games I definitely want to play soon)
Cards (duplicate entries for any games that I haven't earned the cards for yet)
Full Games (for real, good, big titles)
Small Games (for indie titles, short games, little stuff that's still fun)
Worthless (for things I own, but will never, ever want to touch again)
...unlabeled... (new titles I just got and haven't decided on yet)

Don't know if this is any helpful, but if I want to play a certain game genre I use this site that is able to list games you own by official Steam tags. Maybe there is a suggestion in there somewhere.

Why don't you just use steam itself and look at what games are tagged under
