My God, that Gamespot review is absolutely terrible. Oh noes, there are so many moves, me confused. Oh noes, you need to master each character instead of using the same moves with each character in a different skin. Like really, dude?
What's next? This game has so many characters that it takes long for me to choose? Or that game is so addictive I missed my deadline, so I give it 6,5?
That's why Runa is right. Forget about the scores and read some reviews.
