I don't understand why the act itself of putting the DLC on the retail disc is what people usually go ballistic about. Doing this is a good thing, for the exact reasons Capcom stated.
The problem isn't just that the content is on-disc. The problem with
Street Fighter x Tekken in particular is that the content is on-disc, complete and ready to use, but no one except pirates and people with modded consoles can use it until after the Vita release, which is at least
six months from now.
This is made
worse by their reasoning, not better. Not the "no one has to download stuff to play online" thing, which makes enough sense. I mean the "breathe new life into the game" line. Disregarding the fact that this is PR speak for "make us more money," this to me says they don't think the game is strong enough on its existing merits to survive for six months after release—logical for something ultra-mainstream like yet another
Call of Duty clone, but silly for a fighting game—and that the correct way to solve this is to have expansion content ready to go at launch.
Really, all of it makes me glad I don't have any interest in playing
Street Fighter x Tekken, a crossover involving a series I don't like and a series that bores me.
