About seven months ago, I posted a blog called "By the Numbers" that looked the statistics produced by Giant Bomb's Xbox achievement tracker. Since then, I've done a few other stat-based blogs, but I think now would be a good time to go back to the original idea. Let's look at the achievement tracker based on the year of 2011 as a whole. What were the most played games? What were the least played games? What were the most completed games? Or what if we take a glance at how a Quick Look might affect how people decide what to buy?

By my count, there were 185 games released for Xbox 360 this year. I'm probably missed a few, but tracking down that info is harder than you think. Either way, we've got a pretty good population of data to make some accurate observations. I decided to only look at Xbox because not everyone on the site has access to the PSN tracker yet, and if I were to add in Steam stats, it would skew the results since I'm already not including all platforms. So, including just the Xbox stats makes it easier in several ways (i.e. I don't have to do a whole bunch of math).

Also note that, unless otherwise specified, these charts include both retail releases and XBLA releases.

Anyway, on to the numbers...
