An amazing sequel.
Take the already perfect formula of the first Viewtiful Joe, add the ability to switch between Joe and Silvia, mix in some new moves, and add the Six Machine as a weapon and you get Viewtiful Joe 2. The gameplay is the same, with new stuff, making it better than ever before.
Graphics:
The same style as the first. Hasn't gotten any better, and it hasn't gotten any worse.
Sound:
Great music, SFX, and voice acting yet again.
Replay:
As with the first game, there are unlockable characters and difficulties that will make you want to play through this one again and again.
Overall:
Viewtiful Joe 2 is a better game than the original. It may not have that awe and shock sensation, but the formula is the same with improved gameplay elements. BUY IT!
