Edge and Electronic Entertainment Design and Research have teamed up for a series of weekly quick-to-the-point graphs that highlight certain market interest areas or trends.

In this first week, we ask: If your videogame-illiterate Aunt Sheila walked into a store and bought you an Xbox 360 game, what are the chances that it would be a quality title?



As seen in the graph above, from 2005 through 2008, 13 percent, or 48 of the games on the Xbox 360 have received an aggregated review score of 85 or higher; 38 percent of games have received a 65 or lower.

Next week: How does the PS3's software quality stack up?

Note: Special Edition SKUs have been removed so that multi-SKU platform titles are not counted twice (I.E. Guitar Hero: World Tour has 3 SKUs on the Xbox 360).
