Personally i think that it shows an interesting link between the american and japanese cultural aspects of gaming, and, some unusual crossovers. While japanese games (from nintendo) are more about treading the zombie grounds of the nineties, remark how the american franchises of fighter games are very limited in this platform. Which is odd, because of their general sucsess (see powerstone dreamcast - which wasn't that sucsessful, but rocked).
There... can that be why?
I'm gona stick with link. Will many people be changing their main characters?
