All 1000 of them. One category games = crap.

I only have 1 crap game, and that is Terraria. Wish I could get rid of it.

I got Civ IV complete and it put 3 extra copies in my list (that apparently are for macs), so those are in my junk category.

I haven't a "Crap" category. I find this offensive. :P

But my "Trash" category is filled with Left 4 Dead 2 Beta and Counter-Strike: Condition Zero.

WTF WHY IS FORTIX IN THERE???

So many free greenlight game.

Half of my steam library is crap..

None. I don't categorize.

Blasphemy, Fortix?

None. Why would I buy crappy games in the first place?

You mean Deus Ex Human Revolution, right? I mean, the Director's Cut doesn't include the original Deus Ex I think?

In my case, I have English Country Tune, Fortix, Oil Rush, Patrician IV, Anno 2060.

More than I'd like, unfortunately

Most of these games I at least tried, but they weren't for me. Some were blind ninja grabs, which, if I had known the game, I wouldn't have taken. I try to be at least a little selective about what games I activate, giveaways I enter, and I don't just activate entire bundles for collection sake. Moving games into this category helps manage the backlog, some.

A Virus Named TOM
Bastion
Dwarfs!?
Enclave
FTL
Puzzle Agent
Rush Bros
Thomas Was Alone
Tidalis

My shit category

I don't have such category, but if I did, there would be L4D 2, Mirror's Edge and Dino Horde.

So far:

Bit:Runner 2

I have a feeling Post Apocalyptic Mayhem will also fall into that category

Toki Tori, too casual for me, can't stand the pace of the game.

Alpha Prime, Dino D-Day, Hyper Fighters, Velvet Assassin,

I have category shit, what is similar and theres some betas and Unearthed: Trail of Ibn Batuta, Dysan the Shapeshifter and Final Slam 2

Don't have a "Crap" category, but a "Will Never Play" one. Though it's always games I have actually played that go in there :p.
It encompasses all the MAC versions, bad games, really bad games, games that aren't my thing, and those that make ma want to strangle someone from the dev team.

I have a category for "extraordinary" games.
FootLOL: EFL, Mitsurugi Kamui Hikae and Postal 2 are in it. Mostly just to show off the oddest and most interesting games in my library.
Crap? Oh, I hope I wont have to go through it.

Don't have a crap category, all my games are categorized according to genre. But if I was to make one it would have such "exquisite" games like: Takedown Red Sabre, Orion Dino Horde, Dino D-Day, Counterstrike Global Offensive, Alpha Prime, Chrome Specforce, Clive Barker's Jericho, FEAR 2 Project Origin, Natural Selection 2, The Ship, E.Y.E Divine Cybermancy, Garshasp The Monster Slayer, X-Blades, Sleeping Dogs(might have actually been a good game, if it didn't have so many deal-breaker bugs), Section 8, Killing Floor, PAM, Pixel Junk Monsters, Pixel Junk Shooter, Arcania Gothic 4, Risen and Risen 2, Game of Thrones, Anomaly: Warzone Earth, Shad'O, Sang Froid Tales of Werewolves.

Keep beta and test versions in a Garbage section. Used to have the Mac versions of GTA and Civ games, but seems Steam fixed them appearing in my library. Besides that I just keep games I damn well know I like in favorites, and everything else uncategorized.

On a side note, I'm always so happy to remember that I helped fund the Kickstarter for Takedown: Red Sabre. So fucking proud ...

Cities in Motion 2 is in my crap category, it just sucks. Terrible intro to the game and terrible tutorial. Never hooked me onto it.
