Addendum: 360 Game sales et al

To put all that game sales stuff in perspective, let's look at the worldwide sales figures for the overall  best selling games for the Xbox 360 that went over four million sales.

Fable II 2008  4.12
FIFA Soccer 12 2011  4.08
Fallout 3 2008 4.05

Forza Motorsport 2 2007 4.00

This is a "top 30" list, because the first title comes with new sales of a Kinect.  So any fan of any genre (even those who, say, bought a Kinect just to give voice commands in Mass Effect 3) "bought" a copy of  Kinect Adventures when they got the sensor.   That figure likely also includes console sales of  any of the Xbox 360 + Kinect bundles.

What this tells us is that historically, people who play games on this particular console, do so to large extent for games like those genres listed above.

If you just want to go with the sales figures for North America all consoles, in November 2012 "Amazon online sales data" (for week 45 it was said) looked like this:

1. Halo 4 (Xbox 360)
2. Assassin’s Creed III (Xbox 360)
3. Just Dance 4 (Wii)
4. Assassin’s Creed III (PS3)
5. FIFA Soccer 13 (PS3)
6. New Super Mario Bros. 2 (3DS)
7. Madden NFL 13 (Xbox 360)
8. Pokémon Black Version 2 (DS/3DS)
9. Elder Scrolls V: Skyrim (Xbox 360)
10. FIFA Soccer 13 (Xbox 360)

Which might also give us a clue as to what kinds of games might go with what kinds of consoles, at least in NA.
