Over the holidays I bought way too many games during the holiday/boxing day sales... Here's a list of games I bought and whether or not I've finished them yet...
 
Halo: Reach (Finished)
Fable 2 (Finished) 
Uncharted 2 (Finished)
Super Street Fighter IV (Finished it with a few characters.. not much else)
Brutal Legend for $8! (probably about 25% into the game... kind of lost interest but will probably go back and finish it eventually)
Assassin's Creed II (Only played the intro) 
Dragon Age (Have played a few hours. Loving it... was waiting for PC upgrade to play more. Should play this much more now)
Battlefield Bad Company 2 (Played through a good chunk of the singleplayer game and then lost my save file while upgrading to new computer)
Raskulls (about 80% finished story mode) 
ilomilo (75% done)
World of Keflings (I think I'm about 90% done this... have been playing it co-op only with girlfriend) 
Blood Bowl: Legendary Edition (Have barely even started playing around in this yet)
Bejeweled 3 (many hours of this on laptops over holidays)
Planets vs Zombies PC (Have actually played through this before but bought it again for Steam Achievements... I am a sucker)
Alan Wake (Have played a few hours of this, really like it, but haven't had time to play more)
Enslaved (Almost done! I am playing this more than anything else right now)
WoW: Cataclysm (Played this a bit before Christmas and mean to get back into it more, great stuff but not time to play (see above))
Lara Croft and the Guardian of Light (Bought this super cheap. Haven't played too much yet. Was hoping to play co-op with someone local) 
Kinectimals (I bought this mostly for my nephew who played it over the holidays. Haven't played it since I got back)
Dance Central (Was really sick recently and haven't had the energy, plan to have people over to play soon though)
Kinect Adventures (We played this a LOT over the holidays... my parents really got a kick out of it)
Lego Universe (Bought this to my nephew but he's too young, ended up playing it quite a lot during 30 days included. Did not renew though)
 
I bought more on Steam but that's all I can remember at the moment... In most cases I paid between $1-10 for each of these games on sale in different places... I don't plan on buying anything else for a while... these should keep me busy...
 
It's a pretty strange mix of older games, new games and casual games... I am starting to notice that I have no specific taste in gaming... as long as it's good.
 
I had so much free time over the holidays it was awesome to play so many games... but there's no way for me to keep up the pace I set recently...  these games should last me months now...
