Well, they keep last years game or the one before it VIABLE as an option to the newest release...which is why they don't want it. AND that is also why they won't fix ALL the bugs from one year to the next. If they made even a NEAR perfect game they wouldn't sell as many copies the next year cause there would be hold overs from the previous year.
I say that like its fact...I should add, its just my opinion(and sad that I had to add that, sheesh).
