There's a popular Flash game simply known as "N", you may have played it before, if not you are sure to at least try it out this fall when it comes to the Xbox Live Arcade. Metanet Software is teaming up with Vancouver based developer Klei Entertainment to produce the title.
To the fans, they promise to keep it as close to the original as possible. They also will be including a level editor so you can make your own maps on your 360. This seems to be the first game promising user created content so I can't wait to see how this will work. They are also trying out multiplayer modes so hopefully we'll be playing together later this year.
Development will start on this title the first day of February and should be finished by the end of the summer.
