I'd personally suggest RTCW: ET - the great part about it is that the FULL version will be released absolutely free of charge REALLY soon, which means that it's still a full game (better when compared to demo), while still not a retail game (aka you don't need to own a copy, or scavenge CD keys from friends like certain people on those forums I believe do :P ). And the gameplay is really great, I seem to enjoy the game alot, as well as the other guys from our forums that tried it do.
