The final boss, Seth, was made a lot tougher in Super Street Fighter 4. But you do not have to fight him over and over to unlock the last playable character, as they will all be unlocked from the start.

"Seth will be even more cheaper and irritating," Capcom said. This is strange because the boss was already a huge challenge and annoyance in Street Fighter IV, so it makes you wonder why they would make him even tougher!

But as long as all of the characters will be unlocked from the start, maybe it won't be so bad.
