It appears to be a "neutral" planet. Anyhoo, while Predator remains a classic, it's sequels aren't great. There's a great AvP graphic novel made from a script that was rejected before Alien 3, that had Ripley crash on a planet where Predators were hunting Aliens.
It was neat.
But I must say, for what it was, AvP 2 amused me.
