Talking about the score saving idea for a second...If I gave a little bit of code that you could just paste into a script that would save peoples scores (from an rtb approved addon, btw) and would set joining players scores to their score when they left, would you be able to use it?
speaking of a buy system, HellsHero was working on one, and so far I haven`t heard about any progres yet.
Did I mention that it was also CS:S like?
You could set any weapon to a price
