I understand that, but like ZombieSupaStar's excellent XCOM parallel, why is this called SSX? Call it Deadly Descents, job done. Using the SSX IP does attract a preexisting fanbase to this product, that is fair enough, but if they're not happy with the direction, they're going to be pissed off, and still not buy it.
If this is a hit, it's nothing to do with the SSX prefix, the worst that could happen is you have a second snowboarding IP that isn't so highly regarded, the worst this can cause is to fuck up the one they have.
It just seems like a very poor decision to me. But a lot of people a lot smarter than I'll ever be decided this, so maybe I'm well off the mark.
