[QUOTE="WonsAuto, post: 0]sKotaku brings up some perspective, but here's another: while only 17% of games on 360 are shooters (11% FPS, 6% 3rd-person), which are the ones that are the most hyped and best-selling? Games like GRAW, Gears, and Call of Duty sell a lot more than, say, Viva Pinata or Project Sylpheed. So while there aren't as many shooters in terms of IPs on the market, they definitely dominate the Xbox 360 market share, which is why they're so readily associated with the system.
Not exactly fair, but those are the breaks.[/quote]
Exactly. Plus there is another thing at play. When you look at sports games (which dominate), you will likely only get one of several options in a year, Madden or All Pro Football, not both, whereas Bioshock and Halo 3 will both be purchased, despite being in the same genre because they are very different.
A better analysis would be percentage of games sold, or shooters per owner, rather than shooters available.
Another good analysis would be lets say to go to Metacritic and take all games above 70 or so score, and see percentages there. Then you would look at good games with effort into them and see how they fare.
