Anyone following this sale as obsessively as I am?
On Steam, the best discounts are given in the Summer and Winter sales. That's really the time to buy. Everyday until the 10th they have new daily deals, further discounting games that are already on sale. It really tests your patience.
I'm keeping an eye for a daily deal on these games: Portal 2, Two Worlds 2, Terrania, Dungeon Siege 3, and that's all that comes to mind in terms of games I want but down own.
