I recently purchased the XBLA title N+, and I must say that I am really enjoying it. The premise is simple: guide your ninja character through various obstacles and traps to unlock an exit door. The game itself features 45+ single player episodes each containing 5 levels and many more multiplayer levels. Also included is a level editor where you can create a level and presumably send it to a friend over live. The only knock on the game is the rudimentary graphics, however, the sheer volume of the game makes it easy to overlook the graphical short comings. To say this game is addicting is a vast understatement, the varying degree of difficult and interesting level design make the title a must have for any Xbox Live users.
