The thing is there games have ever sold. Godhand was a flop, Okami was a flop on ps2(they didn't make the wii version), viewitful joe was a flop, and Madworld didn't sell much. These guys don't make mainstream games. They make artistic games that the mass won't buy.
They need to make a competely new game on the way that the masses would buy. Madworld 2 will sale less than the first.
