MW2 is retailing for $69.99 CAD (about £40.00 GBP) which is at least $10.00 more than I'm willing to shell out for a video game, thankyouverymuch. Activision is obviously taking advantage of the pound being worth more than the dollar, but I think it might just backfire on them.
Holiday shopping frenzies aside, I think most people (Except for the upper-middle class types who give their precious snowflakes anything the little shits want) will wait until the price goes down after Christmas, which will be the big litmus test to see if the price gouging holds up or not. I'm guessing it will, just based on the aforementioned ineffectual parents with credit cards, who will buy their brats anything no matter how pricey.
Ah video games, we love you. We hate you. We need you, but we aren't your *****! Developers need to start realizing that reasonable prices equals profit, because more people will buy your product if they don't have to take out a second mortgage or give up on say, eating for about a week. Yeah $90 isn't that big a deal, but that's not the point.
Slapping an unreasonable price tag on a game just serves to alientate those of us that don't have tons and tons of disposable income, and we're the main demographic these guys are catering to!
