Demon's Souls and Dark Souls director Hidetaka Miyazaki told Edge that he doesn't the Dark Souls series to balloon into eight different games. Dark Souls 2 is the first game that he won't have direct control over, and he said he's excited to play it, despite his reservations over the series becoming too big.
