I don't even think it's ego . . . money, maybe, because of some marketer's idea of pragmatism (which will drive any game publisher -- other than EA -- in the ground, mark my words; that said, mimicking EA ain't gonna get you where you wanna go).
If the argument is that the game will suck because of designers' egos, I hope they'll hear me out when I say they'll get much better ego-ROI by making a game we're asking for. People will buy it, and they'll love it.
You ignore us at your own peril ;-) (and that's me addressin' your EGO back there, devs :-)
