Whomever saw the thread I'm talking about with the key "DEII6-KHNTF-5BJAB" is probably puzzled (as am I) as to what the key really was. It wasn't BL2, since I don't have that and Steam said I already had whatever the key is for. Steam also said to 'click next to proceed with installation', but there's no next. Which could mean it's a game I already have installed? I currently have the following actually installed:

• 1... 2... 3... KICK IT!
• AaaAaa!
• AaaAAAaaaaaaaaaaaaaaaAa!
• Avadon: The Black Fortress
• Beat Hazard
• BEEP
• BioShock
• Blocks That Matter
• Braid
• Cthulhu Saves the World
• Cubemen
• Dead Horde
• Dino D-Day
• Dwarfs?!
• Eufloria
• Evil Genius
• Faerie Solitaire
• Fallout
• Fortix (1 and 2)
• Guns of Icarus (regular and online beta)
• Jolly Rover
• King Arthur
• LIMBO
• Lucidity
• Orcs Must Die!
• OSMOS
• Plants vs. Zombies
• Poker Night at the Inventory
• Portal (1 and 2)
• Post Apocalyptic Mayhem
• Q.U.B.E.
• Runespell
• RUSH
• Sanctum
• SotMC
• Sequence
• Serious Sam 2
• Snuggle Truck
• Solar 2
• Space Quest Collection
• Spore
• SW: KotR
• Terraria
• Toki Tori
• Torchlight
• Trine 2
• Tropico
• Universe Sandbox
• Uplink
• Vessel
• VVVVVVV
• Wonderful End of the World
• Zero Gear

If you have some of these but not others (and/or you have some installed but not others), post here. Maybe we can figure out what the key was really for. ;)

Think of it like a really horrible It's Too Hard puzzle, haha.
