Id Software has done a very good thing by making its Quake Live beta free. You simply register, download a plug-in and let the game begin. The shooter has 40 arenas and 5 game modes from beginner to pro skill levels. You can also practice and compete against automated bot players if you are the shy type or a newbie. The site already reports heavy usage so be patient. Then practice up and you can participate in their free Quakecon, which will be held August 13 through 16 in Dallas.
