The design of Rare's N64 FPS games is outdated. You can tell by playing Perfect Dark on XBLA. It's only fun if you played it when it was released and hence are overwhelmed with nostalgia, or if you are led to believe it was made by only a few people. If they remade it and kept everything how it was, a retail release would just feel like theft. Whereas if the developers make something where they have a little more creative control, we might not get a soulless update of a fond memory.
James Bond blows.
