The developers and fans of Enemy Territory: Quake Wars do not want the game to be compared to any of the Battlefield (1942, Vietnam, 2) games. Unfortunately, they built a team based multi-player shooter that has vehicles and unit classes, so comparisons are imminent. After all, Battlefield 1942 sort of defined team based multi-player shooters with vehicles and unit classes. It may not have been the first, but it was the most defining in my opinion.
Whether players believe ET:QW is anything like Battlefield or not, for me, there are enough comparisons to be made. Honestly, both games play the same. In Battlefield you are advancing from flag to flag. In ET:QW you simply advance from objective to objective. ET:QW has the benefit that objectives are a lot more interesting and can change on the fly. For example: the demo map has the GDF forces charging forward to build a bridge in order to advance on to securing the bridge, followed by advancing a mobile base.
Err well, I think those are the objectives. Battlefield's flag capture system may be static, but at least it is understandable to pretty much everyone. The objectives in ET:QW tend to be confusing at first and confusing in the end. Players can hit the "m" key to select a new mission (objective), but often times missions disapear as the objectives are met. As a new player, I spent most of my time confused on what I should be doing. There is little guidance to indicate what objectives need to be done or in what order they should be done to maximize effect. I guess it is up to the players to figure out?
