Sorry but, I disagree, strongly.
The general game buying public buys what's familiar.
Sequels rule the world.
Game publishers are afraid of taking chances on games that aren't sure bets. Games that sell millions of units are sometimes being called failures at this point
So, the question is, do gamers hate innovation or do publishers never iterate on games that don't blow the roof off the the sales charts?
Without iteration, franchises can't get footholds and massive sales are unattainable.
This isn't a fear/distaste of the innovation contained in these new ips, it's a lack of awareness they exist. It's tiny marketing budgets and the realities of franchise momentum.
Plus, there is the question of who a gamer is. Parents know the big franchises and grab them up at xmas. Those purchases aren't being made by the end user.
Some would also argue that the massive sellers also appeal to "casuals" so therefore might claim, that sales at the extreme are not a valid metric for a discussion about gamer's tastes. This is a bit, of a gray area, personally.
