Buy it online, play it offline. The game you learned to love, but do not play it over Live.
They failed.
The offline game is the one you learned to love: Ryu, Ken, Guile, Sagat, Vega and etc. They are all there, with the bonus rounds and the catchy sound theme.
Good controls and the game a little faster than the normal one.
The online game is the one you'll learn to hate: Lag, lots and lots of lag, glitches and slow menu transitions. Man, what a let down.
Lets hope they can fix this over the time with some online updates. Enough said.
