Goldeneye - great multi with friends and great single
Half life - best singleplayer ever, immersive as hell, alot of content and replay value
AvP 2 - fun multi, great singleplayer, scary as shit, and immersive.
Notable mentions
Far Cry - great start of singleplayer, crappy ending levels of the game
Medal of Honor AA - great multi and fun experience
Perfect Dark - best fps of N64 Generation consoles, but not as big as Goldeneye
Battlefield 1942 - great
Deus Ex - best story ever
-Goldeneye
: In my opinion, a pioneer in many areas. I played this for years, and I still occasionally play it. Perfect Dark is the best N64 game other than this one, IMO.
-Unreal Tournament 2004
: The first one was good. 2003 went off track. 2004 has the same great feeling, with powerful additions. Lovely. But they need to lay low on the Onslaught mode and remember this is primarily a FPS.
-Aliens vs. Predator 2/Primal Hunt
: I play this almost every time my friends come over. Queens and Exosuits are the coolest thing ever... Plus, any time a newbie comes over, we scare the sh*t out of him by all being Aliens and making him a Marine. 😈 "Bing! Bing! Bing!" "What the fu-" "MC Mike just slaughtered Newbie 1" 😛
AvP has great multiplayer. The unique sides that play completly different than each other.
The best is when you get a group of marines together and you slaughter individual aliens. They dont stand a chance. one with a pulse, one with a smart gun and the other with sniper...and maybe some more pulse rifles for good measure. Great game.
or hunting for the predator as a group of marines.
