Missed out of those Microsoft Store deals: They had Tekken Tag 2 for $10.
Really didn't spend much this year myself since I still have a boatload of backlog games from last year's deals.
This year's booty:
Left for Dead 2 (PC since all the DLC packs are free anyhow) $5 from steam.
Starcraft 2 $20 (PC--Battle.net sale)
Trine 2 Expansion Globin King $4 (PC steam sale, in fact you can get the entire series for $8).
Mass Effect 3 Leviathan $5 (360--XBL sale)
Batman Arkham City Harvey Quinn Revenage $5 (360--XBL sale)
Total $40 for 2 games and three expansions.
Going head to Target today, hopefully they have more MS point cards (they ended up selling 1600 point cards for $10).
