I thought people generally stick with just a few shooters on one console at a time. If that's the case, I'd say having GoldenEye, other James Bond games, and Perfect Dark is plenty, especially considering that people are still playing Perfect Dark, albeit now over on the XBox.
Still, I'm not familiar with other N64 FPSs, but really, only one or two FPS seems to stand out each generation, anyway, from my perspective.
