I love this idea shortbus.

My only issue would be to how the admins would go about giving non-admin players a skin..they would have to login somehow. I don't know if this is possible, someone correct me on this if I'm wrong.

It'd give players an actual desire to play the game more, and do well. There is another issue however with the scoring on the gungame server. The game doesn't reward knifing and winning point-wise very much, and when you get near the top 20 in the scores, you lose points like crazy if some random comes in and owns everyone. Though this can't be helped, if someone were to actually implement a system to where points MATTERED, then a point balance should be in order..
