What have you already bought on Steam Summer Sale?

Antichamber, Defiance, Euro Truck Simulator 2 and Scribblenauts Unlimited.

cs go

I'm holding off on Terraria. I'm waiting to see if it go 75% off. I think it will sooner or later.

Dark Souls, Don't Starve.

CS:GO, wanted to get Borderlands 2 but I was disappointed it was only 66% off. Considering that it was $15 with Season pass on GMG a week ago I was hoping it would go 75% off. I might get it later if I don't find any better deals that interest me.

Civ V Gold Edition and Portal.

Antichamber and Scribblenauts so far! I've bought most games over the last couple of holiday sales from Amazon and GMG, though. And GOG.

TF2 Keys

Nothing.

A card from the market, nothing else, still waiting for a Tower Wars 75% sale
