The argument that Mario Galaxy 2 is an add-on type game to the first one... Pu-lease.
You mean it's not the same for Modern Warfare and Modern Warfare 2?
God of war 1, 2 and 3?
Ratchet and Clank Tools of Destruction, Quest for Booty and A Crack in Time?
Shall I go on and on?
The entire rant about Galaxy 2 is completely devoid of logic and seems to me like it's more a vendetta or agenda against Nintendo than anything else.
