Jedi Academy CTF was one of the best CTFs that I've played. Strafe jumps, force, all weapons, fast gameplay etc.
I believe that people are still playing some PUGs.

And Movie Battles 2 mod for JA was/is great! Too bad that competetive scence died couple years ago.

Last time I loaded up Jedi academy there was a couple active duel servers. We were lucky to play this when it was active. Very fun times.

I mean, JA engine is literally the Quake 3 engine.

did you mean java? java quake engine would be actually cool to revive idea of a browser based quake game, i just check this site and it looks playable http://www.quakejs.com/
