It's an interesting concept, trying to prove and believe that humanity on the internet is still capable and functional to be intelligent and respectful.
While my optimism is high for this event, I personally hated CS:GO, and haven't played very much of it compared to the amount of CS:S I've played.
Might be a better platform to attempt on CS:S, considering the hacking and griefing, but then again admin's are more prevalent on CS:S per server, so ... meh?
