Brilliant. I like the sound of it already.
That's the one thing I love about those certain FPS games, you're not forced to kill eachother, there is one point of the game where you can just forget around with firearms and test them out, and find one that you really like.
With games like CS:S, they're all pretty much the same, and you never get time to play around with them.
Edit: Also, variety of weapons?
