A game that remains to this date one of the best games ever made, still being insanely fun. A classic not to be missed.
The fun that can be had in Quake 3 with the intense online action, custom maps, gamemodes, etc, is amazing, and remains so from day of release to the present day.
I have had Quake III since the day of release, and I continue to play it today. That's a good 9 years without it getting old/stale and playing it very often. As I said, it has intense usually close-combat action which is very well done, very fun, and very fast-paced, and not only that, but it's highly moddable, making maps and textures and sounds and models and just about everything in the game is easy to do, however the fact that it's easy doesn't mean it's simple, you can still make very high quality stuff with it.
All in all, this game is simply a classic and a masterpiece, and will always remain so in my eyes. No online experience is really quite like it.
It's still highly played today, still fun, and other games like Unreal Tournament really don't live up to it, and Quake 4 by Raven Software didn't live up to it.
This game gets an easy, perfect 10 from me. This rating may seem like a premature judgement; but believe me, it's not. This game is so good, I can't see it having any possible improvement, therefore it earns a 10. I don't think i've ever seen any other game get a 10 from me.
Don't think twice about buying this game, even today, it still is WELL worth it.
