God DAMMIT SNK needs to stop this. Every time, they do this: they start with the initial chapters, then inch along to the ones that people actually want, but they often don't even make it to that point because they give up long before then.
Nobody wants Samurai Shodown. Nobody wants Fatal Fury. And if you do, you're a weirdo and part of the problem. There are enough good games that people actually do want that you've got plenty to release before people get bored.
