Topics included new Blood Sports maps, the day/night cycle, supercross, pop culture references and questions about the art and graphics of the game. One of the questions wondered why they couldn't add more body types into the game, which earned a revealing answer: "If we do implement new chracter [sic] types, it will require new rigging, new animation (about 1000 of them), and new boltons just for one new toon. You'll notice that games like Gears of War and Halo only have men? That's because they couldn't even afford to spend time doing a female toon. It's a LOT, LOT, LOT of work."
