The idea of gaining access to a ton of downloadable content by paying one package price has worked out well. Just ask Activision (Call of Duty Elite) and EA (Battlefield Premium).
And it seems Ubisoft will be next on the bandwagon. In an appreciative note the publisher sent to GameStop stores (as leaked by Kotaku ), they first thank the retailer for hitting pre-order goals. Employees get a little bonus for that, too.
But it's also clear that Ubisoft will be spending a fair amount of time producing extra content for the potential Game of the Year contender. In fact, there will be enough to warrant a "season pass" of some kind, which we have to assume would act very much like other DLC promotions. It doesn't specify what sort of DLC we can expect, but remember that Ubisoft has released extra single-player content for previous Assassin's Creed installments, so we're moderately enthusiastic.
Well, when games are this big and sales are expected to be in the 8-10 million range lifetime, DLC is probably a must and a whole lot of people will want it. Will you?
