I just bought XBox Live today for use with RTCW (although I'm used to the PC's Enemy Territory version of RTCW and have no idea how to play the new maps).
But the kit came with a near-full version of a Live-enabled Tetris game. It was absolutely spectacular: at most a 0.5 sec lag between speech and the quality was a bit better than phone. Best of all, XBox Live requires broadband and initial payment so the cursing kids were nowhere to be found![]()
