PlanetSide

I recently bought PlanetSide, and and so close to beating Vice City, but the game never ends. It just keeps going and going and goind. You think you're out, but you get pulled right back in. VC can do that. But that's besides the point. Concerning PlanetSide. If anybody has it, or knows somebody who has it, could you tell me an estimate of how many people play (on average and anytime)? If you don't know, could you tell me where I could find out?

Edit: I just want to know if there are a lot or a little people playing. I plan on returning it if no one plays it. Thanks.
