Yeah natural Selection is pretty popular with several of the Savage players. I'm a big fan of the Aliens movie, so NS is definately my kinda game!I've played loads of Natural Selection. It's alot like Savage, except based in in the future with Marines and Aliens.
Commanding other humans is much fun, even when thay don't follow orders
Even though people don't always listen, with voice comm it's nice to be able to tell people to go do something rather then have to click them and interupt something your working on. But you definately get people who piss you off by not listening to you and doing there own thing! It's definately interesting to work with actual independently thinking minds rather then just AI.
Clan matches are pretty fun for Savage as well since the entire game is base on good team work.
