I just started with the Planetside 2 beta, on J's suggestion. Not for lack of desire, I haven't played Battlefield or CoD online so it's my first MMOFPS experience. It's pretty good, there are a lot of cool mechanics, although the gameplay isn't Bungie-slick.
The world us divided into a handful of continents that are eternally embattled. The members of each faction can take and defend the many locations on the map. So the action/movement is focused but contiguous and always in flux. I don't know if any strategies (or rewards, for that matter) have emerged for taking an entire continent, but this would be fun to explore.
