Yep, that's right. I, normally a UT player (2k4 best ever!), am now doing Quake Live. It's very old school graphics but that is nice because it makes it VERY easy to run (quake 3 graphics). It runs even in your browser (default)!
If you, like me, are sick to death of god awful FPS games like CoD and Battlefield and other wannabe FPS and actually want something more along the lines of testing your skill and ability (master strafe jumping or die....even I have yet to master it...) then Quake Live might be your thing!
