Worth the challenge!
Gameplay - Much much more complex than the previous games, it is harder, and much more rewarding to learn. The counter system seems nearly impossible to learn at first, but give it time and you will learn to love it. The finaly boss (alpha) is extreemly difficult at first, but after a while you will wonder why you lost so much at first.
Graphics - Amazing! yet graphical flaws (such as your clothes going thru yourself) prevent them from being perfect.
Sound - By far the weakest aspect of the game. all of the voices are done in japanees, yet when you unlock the character voices (for who says "you win!" etc...) they are in english and dont even really sound the same. i can respect wanting to keep the original voices, but reading subtitles gets old, and the music in general just isnt all that great either.
Value - Endless! in order to unlock everything (i have not yet done) you have to beat the game countless times on every mode, each character has tons of clothing options that you can unlock, and the ranked muliplayer online is a very nice aspect to mess around with after you get a hang of the fighting system.
Tilt - I really liked the game a lot, and still do. I play it more than any of my other Xbox360 games right now (although GRAW is not out yet), if it werent for the poor sound and graphical errors, this game would be up their with the original Soul Calibur on DC. Yes... it is that good!
