Not nostalgia for me, I play Quake 3 about 15 times a week with a group of people, it's still awesome fun. We're all so good at it, it's genuinely a difficult competition every time. After 15 years we still get in ridiculous/interesting situations in the same maps all the time.

Same here. My BFF and I have played Q3 on and off since it was released. But we've clocked more hours in the past couple years than in the previous ten.

Even after all this time we have a blast and sometimes situations erupt into huge bouts of laughter. I'll never not think that an errant rocket splash knocking him off the map is hilarious.

same here thanks to fpsclassico theres still a vibrant community

Someone (you?) linked this here and I ended up buying Q3A and running it through ioquake. Quite a blast, even with just bots.
