Looks like a cool idea to me. Caporeia is so much fun to watch, and Tiger/Eddie Gordo was one of my favorite characters from the Tekken series. The only thing I could do without is the "underground fighting" arena idea, but I'll get over it. Since it will be available on the DS, I may have to look into purchasing it. Perhaps it is an idea that they can carry on with other styles as well; a Boxing one would be good, Karate and TKD could work well, too, I think. Loads of possibilities, if they are willing to pursue it.
