Actually, if you want to break all this down, it\'s not in the same ballpark. Why you ask? Consider this...
Capcom considers Mega Man three different franchises. What you ask? There is the "classics", "X" and "Battle Network" series. Each is its own franchise and that is how Capcom thinks of them. The same can be said about Street Fighter. You have Street Fighter 2 , Street Fighter Alpha and Street Fighter EX. Each is its own distinct series, with distinct characters and adjustments to the gameplay. That is why Street Fighter 2 was eventually followed with Street Fighter 3 and Street Fighter Alpha was followed with it\'s own sequels. Where am I going with all this? Midway has kept the Mortal Kombat franchise as just one single franchise.
I know there was no point to this, but I like educating people.
