Well, they made a competitive 'wartune' style game in the form of mononofu, so we could see it coming again on nutaku in form of western game as well...

Those are quite easy to make, since you can pretty much steal... err.. borrow the pre made code base to make it easier to develop the stuff into a basic concept at least... and that's what they usually do - just a recolor/restylishing mostly.

Been times when I actually enjoyed those competitive games, but not anymore... still quite sure that it will have it's own audience, considering how popular was the mononofu during it's prime competition time at launch despite having one of the most horrible jap art on nutaku.
