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 - Get Report) 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 - Get Report) 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.
