Yes
Best case Call of Duty on wii u

That is your best case? Really?

So why the CoD sales on Wii shrank with every new title? http://www.vgchartz.com/gamedb/?name=call+of+duty&publisher=&platform=Wii

Did the Wii install base get smaller from 2006 to 2011?

Ya his post made no sense, considering this thread is about Nintendo IP and how many times the games sell within a certain range regardless of how big the install base is.
