Video games Common wisdom says there's no better day on the calendar to buy video games than Black Friday. Sorry, but common wisdom is a jackass. Decide put together a great set of graphs comparing this year's hottest games and the price performance of their previous installments during the holiday season. If Activision's ( ATVI) Call of Duty: Black Ops II follows the same path as its predecessor, its Black Friday price will not only hold in most places, but drop even lower just before Christmas. Though Microsoft's ( MSFT) last Halo game was released online, its price plummeted in the days just before Christmas and should give those wishing for cheap copies of Halo 4 some hope. If you're hoping to snag a last-minute copy of Ubisoft's Assassin's Creed III: Revelations, though, prices may not get much better than they are right now. Oh, and forget about a cheap version of Nintendo's Wii U console. If you can find it at all, it will be a minor Christmas miracle. -- Written by Jason Notte in Portland, Ore. >To contact the writer of this article, click here: Jason Notte. >To follow the writer on Twitter, go to http://twitter.com/notteham. >To submit a news tip, send an email to: email@example.com.
