RE: Goldeneye
I never had the opportunity to play through the campaign since I never owned an N64. I played on it briefly at a friend's, but we more or less played split-screen (and of course, he had a huge advantage). Even now, it's notoriously difficult to emulate without lag.
I was pretty stoked when it appeared that it would be remastered for Xbox 360 several years ago, but Nintendo are pretty stubborn when it comes to licensing. Microsoft couldn't reach an agreement with them, and the project was scrapped.
