It's the moment we all dread: Opening a carefully wrapped video game gift from a non-gaming relative. The chances that you'll need to hang onto that gift receipt? Astronomically high -- unless they are given explicit buying instructions. Wishing to put a number to the above hypothesis, Edge and Electronic Entertainment Design and Research have teamed up to graph the Xbox 360 library based on Metacritic scores.

According to the research, 13% (48 titles) of all Xbox 360 software released in North America between 2005 and 2008 have received an average score of 85 or higher while 38% (136 titles) scored a 65 or lower. Of course, this stylish graph only means anything if you take stock in review scores -- and if you follow our WRUP posts, you know we don't. PS3 users don't fret -- EDGE and EEDAR are tackling the big black (on the outside, blu on the inside) box next week.
