There's a lot of exaggerating about this series difficulty. There is definitely a steep learning curve, but once you're past it the entire series becomes very accessible and they're all incredibly fun.
The only reason I knew about the first one was because of this site, but the way things are going I don't think there's going to be any coverage. It's a shame because this one is better than the first in every way except for the fact that pure fist characters don't exist anymore.
But if youve stumbled upon this thread and like the first one you should get it because there is so much more content in this one it's amazing. This will probably be my GOTY and it makes me sad that hardly anyone will play it
