There's a great trend in the entertainment industry to dress up ideas that aren't especially mainstream in new clothes, hoping that, in the end, they appeal to a wider selection of people. Whether it's Westlife recording a swing CD or Hollywood remakes of books from centuries past, there's nothing wrong with a superficial reinvention, as long as it stays true to its original inspiration.
Stinkbot's Sumo! is one such reinvention, putting what is essentially a card game in the clothes of sumo wrestling, and enjoying much success as a result. In short, it's a 'number battler' that requires deft use of strategy and a hard fix on numbers, conveyed through two sumo wrestlers fighting on a bridge - a slightly wacky concept if ever there was one.
