The only thing worse than a crash would be creative stagnation for the sake of costs...
Correct me if I'm wrong, but I think Call of Duty is a decent example of this...
Since the emphasis is on a multiplayer experience that never changes radically, they don't have to put nearly as much care in the single player experience, even if they might claim that they do, because they aren't expected to provide a robust single player experience...
As an added convenience, they already have an engine they can use; would that not cut time and costs (again, correct me if I'm wrong)???
Anyone buying a new COD game already has very firm expectations, and any deviation may not be welcome...
The same can be said for Mario, GTA, Final Fantasy, and Halo, to name a few...
I buy Mario games because I love them, but I still expect to play games that provide new experiences...
But if developers rely completely on predictability, what will happen to progress???
Have a nice day...
