Call of Duty sales started to drop due to lack of innovation, and that was just one series being formulaic. Ubisoft has has multiple franchises that all have the same formula, so they're going to be running them into the ground much faster than Activision ever could with CoD. It's sad that it's not even a joke to say The Crew is Assassin's Creed but with cars.
Yeah, I mean, (some) people on GAF are gonna draw their lessons but I sincerely doubt the general public will react, either because they don't care, they're not aware of the alternatives, they're insensitive to creative bankruptcy, they only play heavily marketed games, they forget easily, and so on, and so forth.
Nothing would make me happier than to be proven wrong, of course.
This doesn't apply solely to Ubisoft btw but also stuff like EA sports titles (by far the biggest offender), pre-ordering broken games, etc.
