-Supreme Commander 2 DLC: Infinite War Pack 1: Adds new maps (which the game needed imo), new units and balanced tech trees around being more diverse which is what I'm most excited for.
-Post Apocalyptic Mayhem: Looked fun, was cheap. I like Twisted Metal, and someone said it handled like Arctic Thunder, an arcade game I really liked.
-Mafia: I like GTA games and I liked Mafia II. So, a no-brainer for $2.50.
-Frozen Synapse: I traded for a friends extra copy, so I only payed $6.72 for it. Don't like it so far, but I'll give it more time.
-Sanctum: Very fun in co-op, until the later waves when their terrible DPS makes you lose
-Jamestown: Haha, fun fun fun incarnate. I love this game. Co-op is a hilarious event filled with random screaming outbursts of delight or astonishment, depending on if you made it out of the latest hairy situation or not.
-Magicka: Vietnam, Magicka: Party Robes: The robe pack is worth it just to play through Magicka as Etzio the assassin. Vietnam, I have no idea about yet, I haven't even finished the main campaign yet.
-Dark Messiah of Might & Magic: This game is silly fun.
-Lead & Gold: Good multi-player. Ways of contributing other than frags adds play-style variety.
-RUSH: I liked Chu Chu Rocket and this game's demo, so yes please!
-And Yet It Moves: Love the art style and the demo was a blast. But it was like $20 when it was new, and was way too short for the cost, so it fell off my radar. Remembered it during the sale.
-Batman: Arkham Asylum: Actually got this game from Gamer's Gate for $5.99 around the Steam sale. I figured Steam wouldn't discount it this cheaply, and I was right. Amazing game! Almost everything about it is fantastic. I've already beaten the game and sent The Riddler to jail. This game made me become interested in the Batman universe, and I don't like comics.
Probably will buy today:
-Assassin's Creed: Brotherhood: I adore the AC games. I'm not entirely sure why. They have several substantial flaws, but I can easily ignore them and get lost in these games.
tl;dr Yeah, I tend to rant. Good sale. Wish I had picked up Darksiders... oh well, it'll be on sale again. This tl;dr isn't really a tl;dr is it?
