If there were any doubt that the Xbox 360 is the home of first- and third-person shooters, let this top five list put that question to rest.
Four of the top five games this year on the Xbox 360 involve guns and explosions and lots of online mayhem. Moreover, they are all third-party titles: Take-Two, Activision, Ubisoft, EA, and UbiSoft.
After examining the PS3 top five, seeing Grand Theft Auto IV at the top of the Xbox 360 list is again no surprise. According to NPD Group figures, GTA4 has sold 4.8 million copies across both the Xbox 360 and PS3.
We estimate that the Xbox 360 version should account for around two-thirds of that total, or just under 3 million units, although neither NPD nor Microsoft have released specific figures.
Moreover, the Xbox 360 version of Call of Duty 4 was in the top 10 from January through April and we know it was above 100,000 units in May. That puts it somewhere higher than 1.2 million copies for the year.
In August the Xbox 360 version of Madden NFL 09 was right at 1 million units, although some of those were the 20th Anniversary Edition which wasn't counted in the NPD data used for this ranking.
We don't have definitive data on the last two titles, but it is quite likely that Rainbow Six: Vegas 2 is between 900,000 and 1 million units while Army of Two is around the 800,000 to 900,000 mark.
