PlayNOW! has posted an interview with id developers Paul Steed and Tim Willits, conducted during their tour of Australia last month. The freely roaming talk covers all sorts of topics, such as working at id, Quake III Arena as well as id's previous games, their gaming influences, and much more. Here is a quote:

Simon: In the short time since its release, Quake III Arena has been hailed by players as the ultimate deathmatch game bar none. You have each commented very publicly that "There will be no Quake IV". Where does the future of multiplayer lie?

Tim: Quake III is probably id's last "I am a one man army with no control or power over the environment around me" game. I think that in the future multiplayer will revolve around more team games, more role-specific type deathmatch where maybe you're the guy who has to guard something for X number of minutes, or maybe you're the squad leader of a team of bots given some mission, or maybe you're a mercenary hired out to some clan or something. I think with Quake III we've nailed down the pure, classic deathmatch style. In the future we can develop new game types or new variants of that, which will be pretty exciting.
