Why don't you support your beloved Nintendo?

[Mnementh]

Well, I see this thread is another: "stupid and evil Nintendo-fans don't buy godly 3rd-party". Well, let's take a look. You claim AC and COD are "the 2 most popular/biggest franchises this gen". OK, let's compare with another 3rd-party-franchise - Just Dance.

AC I (X360): 5.26M
AC I (PS3): 4.52M
AC II (PS3): 5.34M
AC II (X360): 5.07M
AC III (PS3): 4.66M
AC III (X360): 4.14M

Call of Duty is much bigger (>10M per title), but it is also that much, that I don't look into the sales detailed.

Just Dance (Wii): 6.95M
Just Dance 2 (Wii): 9.38M
Just Dance 3 (Wii): 9.77M
Just Dance 4 (Wii): 5.19M

 You see Just Dance is a smaller franchise than COD but bigger than AC and is fully supported by Nintendo-fans. So the assumption to your thread is already wrong: Nintendo-faans support third-party. The 3rd-party only has to care about the Nintendo-fans.

And just for laughs:
Just Dance 4 (X360): 0.84M
Just dance 4 (PS3): 0.24M
Am I now allowed to assume, that Sony- and MS-fans don't support 3rd-parties?
