NonHardcore fans may just casually see a sign in Gamestop and forget the release day. The real marketing hasn't amped up yet, so it's not that big of a deal. Right now a good amount of people know about the game, but we havent seen much of heavy marketing.
I really hate to say it, but the game was going to be trounced in sales this fall. I know thats not a very popular outlook, but any sort of sales it would/will make this fall is going to be overshadowed. We're talking about games expecting to have record breaking sales and we want the Ghostbusters Game to go head on with that?
It's going to do well one way or the other, but I think it stands a better chance not in October/Nov/December/Jan. Pick and choose any of the other months and it's going to be able to escape the shadow of the heavy hitters this holiday season.
Having said all that, I would have rather the game come out sooner than later. I'm in the boat with you guys, just trying to explain basic marketing strategies.
