Turok is one of the first 3D games to come out for Nintendo64. Turok is basically incredible. It's super fast 3D engine with razor sharp graphics sets the standards for today's 3D games. Turok has 14 weapons, 8 HUGE levels(i swear they are HUGE), and tons of bad guys. Turok also has 4 bosses. Some of Turok amazing features are:

High Performance 3D engine runs at 30 frames per second

256 levels of transparency and an advanced real-time particle system create the highest level of realism and pyrotechnic intensity ever

Real-time lighting effects for even more realism

Huge 3D levels with over 5,000,000 square feet and over 300,000 polygons

Over 10,000 frames of 3D character animation

Over 2,000 texture maps create startling diversity and richness

Advanced artificial intelligence allows creatures to see, hear, walk, swim, climb and fly

Enemy head tracking keeps you square in their sights

Animation blending eliminates unrealistic motion and heightens the level of immersion

are to name a few.(actually, i read them from the manual) In my suggestion, you should get this game.
