Pull your eyes away from the Nintendo and pick up a pumpkin, because it's time to get your carve on. Halloween is pretty much the best time of year to embrace your geeky side, so show some gamer pride by displaying your favorite virtual worlds on your front doorstep. That's right, carve anything from the Mario Brothers to Ms. Pac-Man on a pumpkin — these designs will even impress your friends who have no clue what player vs. player means.
