Think the back half of 2012 was stacked with video game releases? It could have been even more crowded. Game delays are common in the industry; publishers try to find the best time to release their big titles to maximize sales. But now it seems no month is safe.

Below are a list of some of the big titles that were scheduled for release this year but were pushed to 2013.

Aliens: Colonial Marines

Then: The long-awaited Aliens game from Gearbox software was originally scheduled to launch this fall alongside the laundry list of other shooters.

Now: Sega delayed the game to February 12, 2013. This was the first time the publisher gave Aliens: Colonial Marines a release date since it was revealed on Game Informer's March 2008 cover.

South Park: The Stick of Truth

Then: When South Park graced our January cover, THQ originally scheduled the game for release sometime in 2012. In May, the publisher delayed it until Q1 2013 and later announced a release date of March 5, 2013 at E3.

Now: Last month, THQ announced it was delaying the release of South Park an additional two months to allow for more development time. It's currently scheduled for release this May.

BioShock Infinite

Then: Perhaps the most famous delayed game of the year. BioShock Infinite won numerous E3 2011 awards and was even given an October 16, 2012 release date. Things were looking good. Nearly a year later, however, 2K pushed the game to 2013 and would not show it at press events until it was ready.
