UT99 is the greatest online multiplayer FPS game of all time. Let's hope that we get a real UT99-2 some day.
Unreal Tournament (also known as UT99 or UT-GOTY -- Game of the Year Edition) is the greatest online multiplayer FPS game of all time. As evidence, enthusiastic players have taken it upon themselves to create tens of thousands of custom maps and mods.
At one time, it was possible to find over 3000 people playing Capture-the-Flag 24/7. The game also had an extensive and active clan scene with competitive ladders and numerous communities and discussion forums, often centering around servers, sprang up.
Sadly, this name never received a proper sequel. UT 2004 is a good game in its own right, but because the movement is floaty-dodgy, creating an emphasis on hitscan ability, ti's just not as good as the Original. UT3 has a good feel to its movement and the game play itself isn't too bad (though not perfect) but, sadly, everything surrounding the game play was heavily consolized, especially the pathetic user interface.
Anyway, the Original Unreal Tournament was a spectacular and very special game and IMHO the best computer game of all time. It was released at a time when the Internet was still coming to fruition and when people were just discovering the potential of the Internet to serve as a vehicle for online multiplayer gaming. UT99 will always hold a special place in my heart and the years after its release were an amazing time to be a gamer.
