Exactly my point. I see this every day when I see the nth installment of Call of Duty and it is simply a steaming pile of crap. Who wants to pay for something he can't even try and there is a decent chance of it being crap?
There are demos, reviews, and about a million voices on the Internet saying the new Call of Duty is crap. If you then go out and buy it then you should accept the risk it might be crap.
