Hmm if you want a good fps that you can play with your buds and what not I would recommend perfect dark and the entire 007 series for the nintendo. However the best fps game I believe for the N64 is Turok 2 its a truly amazing game for its time and has an amazing soundtrack to go with the awesome array of weapons you get to use. Yes its true the game is hard as hell but that's how games were back in the day.
