I'm still can't decide on this, the sales are definitely strong and Activision have definately cashed in exactly how they intended - by making a Call of Duty on the Wii and hoping it gets caught up in the MW2 hype.
The game could have undoubtedly been a better product, it'd help sales but I'm not sure by how much. It's still the best FPS on the Wii market, so it's not like it needed to be better to compete?
On the other hand I sort of see this as the best potential a Wii war shooter type thing could sell. No one can match Call of Duty's brand name, while it had no specific marketing it had the hype of MW2 behind it and the competition couldn't currently be more non-exsistant.
Enter Red Steel 2 to hopefully give me some more insight in this. Red Steel 2 should be the 'better quality lesser brand name' type game to do a suitable comparison too. Hopefully Ubisoft will put some money in the marketing too >_>.
