My, my how things have changed. The former Xbox 360-exclusive Ninja Gaiden 2 is now the PS3-exclusive Ninja Gaiden Sigma 2. Is this the first game that's been able to wear the "Only On" stickers for both the PS3 and 360? Perhaps. While Sigma 2 may be an enhanced port of the original Ninja Gaiden 2, it features a number of new features that are, as the box says, "only on PlayStation."

Most exciting of the new features are the new playable characters: Ninja Gaiden's Rachel, Dead or Alive's Ayane, and Ninja Gaiden Dragon Sword's Momiji. The PS3 version will also feature a new online co-op mode not found in the original that lets you and a friend take on ten different stages. Finally, the game is touting "variable AI," which allows "the gameplay [to differ] each time you appear in a level as enemies engage in a variety of different actions as they assess the situation." Whatever that means.
