Look at Ubisoft's best-selling series. It has nothing to do with Sam Fisher, banished Persian princes or special ops soldiers. It's Rayman.
Second best? Petz!
I hate to say this, but these companies are in it to make money - they aren't non-profits. Why are the PC charts dominated by The Sims Ad Nauseum and WoW this and that? Because that's what sells. EA knows this, and that's why it is the publishing juggernaut it is today.
You can bet your farm that had Microsoft and Sony had known this generation would've panned out the way it has, the 360 and PS3 would have been radically different machines. Why is Microsoft even entertaining the idea of having Wii-like controllers this late into the game?
Fact of the matter is, these companies couldn't give a rat's ass about our gaming proclivities if you belong to the minority, and that's what we are: the minority who would prefer not to play Babies Party. But given how Petz has sold, and given how Ubisoft has to answer not to us, but to their shareholders, this is the type of tripe they have to come out with if they want their stock to continue rising.
