Sorry for the late response. Your point about the low barrier of entry is probably the key here. Other games offered huge lobbies even back then; but thinking back, games like Tribes 2 or Planetside also had a pretty intense hardware requirements and (at least with Tribes) a steep difficulty curve, so not everyone could play or wanted to play.Because at the time it was Battlefield with a Star Wars skin, and it was well executed within the confines of that type of game. It let a lot of people go at each other with a low barrier to entry, when before the biggest multiplayer lobby game was probably X-Wing vs. TIE Fighter.
