Too damn much, I was going to show restraint this year too.
Operation Arrowhead, and PMC for ARMA 2- No more playing Dayz on a friends account for me.
Evochron Mercenary- Procedurally generated Elite-like, sure I'm in, my Saitek always needs a workout
Civ V Gods and Kings: I think I got it at more than the everyday 25% off, maybe 40%?
Burnout Paradise: The Ultimate Box- I've been waiting for this to go on sale for a couple of months now.
SimCity 4 Deluxe- I...I lost the discs, OK?
LA Noire- I bought it to see the faces, I'm not that impressed honestly, still it was cheap enough, and it is a different enough type of game to be enjoyable.
Frozen Synapse: Red DLC- I've been holding out on this one for a while.
Summer Sale Indie Bundle Day Two- Botanicula...aaaand some other games, one was an RTS?
Alan Wake- I don't remember why I bought this, impulse I guess
Trine 2- Bought entirely for the eye candy. Platforming is no good with the keyboard and mouse, and placing objects is no good with the controller, yet it is still fun.
Saints Row: The Third Franchise Pack- An impulse buy and one I do regret, this isn't my type of game.
During the same period as the sale I picked up Skyrim retail for $35, $10 less than Steam's best price. Steam is terrible for AAA games.
