I still play Quake 1 and 2 online, randomly pop into Tribes 2, Counter Strike 1.5....usually the community is clicky and toxic to outsiders but sometimes you bump into really neat people.
Is this game online/multiplayer only? I mean, people still play Galaga and PacMan and other older classic games so why would you think someone wouldn't still play this one too?
It is not online only as we would now understand. But it is certainly only multiplayer game. Well you can play against bots, but even then it is multiplayer.
I was going to mention how much I loved that game, until I realized I played UT99. Time sure does fly...
