Wedgwood: I actually think that Return to Castle Wofenstein multiplayer, which is the first in the series really of these games, was the originator of objective-oriented combat in a multiplayer shooter. So they were the first people to have an attacking team, a defending team, an assault force trying to complete a military objective and spawn waves.
When Enemy Territory was being developed by Splash Damage we added in the notion of command maps and character advancement that again hadn't existed in other multiplayer combat games. So when we went into developing Enemy Territory: Quake Wars we continued this idea of having a plot, a story to really drive the reason that the map exists and that's been our continued focus since the start.
So nothing's really happened as a direct result of what other developers are doing. It's not that we don't pay attention to them because we all play games like Battlefield, but they're just very different games and so the similarity doesn't really dilute what we're doing or what they're doing.
