Having played everything from PONG to BALDUR'S GATE and owned everything from Atari 2600 to VIC20 to Commodore 64 to Amiga to Playstation to PC I know a great achievement in gaming when I see it.  Unreal Tournament is quite an accomplishment for no other reason than stealing the thunder from Quake 3 Arena.  It betters QUAKE in everything but graphics.  It's a pretty close call in visuals too!  Play it offline by yourself or go online and gun down a few strangers, either way it's one heck of a good time.
