2010 had some great games, but it's difficult to award a clear-cut winner. Games like Red Dead Redemption, Mass Effect 2, Starcraft 2, Minecraft, Halo: Reach and more make the decision even more difficult.
Gaming social platform Raptr (http://www.raptr.com) is giving away a chance to win a free game of your choice ($80 or lower) just by tweeting your favorite game of 2010 on Twitter.
