That is very interesting how Level 5 is handling the sequel, to actually force people to beat the original as a pre-requisite in order just to play the sequel. It's nice that they are including the original WKC in the WKC2 disc with the enhancements found in the sequel.
I think how they are handling the online component of both versions of the original WKC is very odd. The fact that both versions of the original game can still communicate with each other via messaging while not being able to play with each other doesn't make a whole lot of sense to me.
