I am really delighted that I've decided to buy this game. In my opinion it beats any fighting game produced in over last 2-3 years. Graphics are great, sound is perfect, fighting is very challenging but as you get into it it is really easy to enjoy every second of the game. New characters refreshed the series so that it is not just another boring outcome. New ultra combos have diversified the existing characters and some of the characters who were clearly unbalanced and overabused (Zangief, Sagat, Seth) were improved very effectively (fe. you can't just spam lariat or send fireballs to win, more of the strikes go through them and it is easier to get things done when you fight a loony who does just that). New online battle modes are really good and they are something different to the concept of the game which makes it better.
My only issue is that some storylines could have been extended by more than just a bit (fe. Akuma - Gouken) and it kind of affects the excitement when you play in arcade mode.
Also I do not really like the bonus modes. I mean.. what's the point of smashing the car or destroying barrels ? This isn't some cheap record-counting game.
N' IMO Seth is still a bit overpowered on medium for any ordinary player. It would take ages to go through him with likes of El Fuerte,
Even though, I have to give it a 5. It would be unfair to lower the grade just, because of my personal views.
