I'm throwing my hat in the 'Goldeneye' ring. What else have people been asking for over the past 10 years? And I'm sure many people here are familiar with the many atempts to bring it out as a mod using various gaming engines, the most recent using the Source Engine.
What a coup if Goldeneye had online multiplayer. I'd be spastic. Of course, it would be better if the Wii-mote worked with it, but I won't be picky.
