Some of the best AI i've seen in a game....

User Rating: 9.4 | Quake III Arena PC
Quake 3 has some of the best graphics, sound, and AI in any FPS game i've ever seen.

Graphics: Absolutely no slowness in this game, and the graphics great enough to let me identify what i'm holding, or who i'm shooting at.

Sound: Reminds me of Unreal, and the voices are really killer...literally. The music is great and the weapon sounds are great also

Gameplay: Quake 3's gameplay is very well done, the AI is very tough your really notice the difference when you pump up the level (which i would not recommend for new players).

Quake 3 is very well done game overall, and is one hell of a classic game.
