SF4 was a new Capcom fighter. It did not play like any game before it. They changed frame data, hitboxes, impact freeze, hitstun, blockstun, damage, life, jumps, walking speed, graphics, etc. Just like SF3 was also a new game, it could very well not have Ryu and Ken and be called something else. In fact, it was not supposed to have Ryu and Ken: they did it cos it would sell more, that’s all. Having new games is not necessarily better, e.g., the first version of SSF4AE. This idea of having something else to play is not very justified, just like waiting for new record companies to release new songs isn’t either: there are tons of older and less known games and music that you can try. It just takes the initiative to search and be willing to learn. You do not need Capcom to tell you what to play. In fact, this Capcom has lost most those guys who developed the games which made the company this famous. In a sense, in terms of what matters - their skill in developing games - they are not really the same company anymore.
