I'm not shure how the pc games work too much, but i do know that the PS2 and Xbox games have to have some capabilities within itself, the only games that work for multiplayers right now like on the Xbox are Halo, and some skateboarding game, but since X-box doesn't have a Server system set up for this yet it's really up to Networking Gurus to set this up themselves at home, A broad band link between people can be setup but each person has to have a small router like a Linux one, and you'll definately need to have some sort of DSL or Broadband connection, cuz dail up bandwith just won't cut-it.
