Killian stated that the game is completely playable as of right now.

The big thing for why they are only 50% complete is that they still have a lot of work to do on features they want to add into the game, as well as new stages and characters.

Street Fighter 4 is surely going to be one of the biggest releases of the year based off reports from early versions of the game.

He stated that "parts of the game are very polished while others are still being developed."
