I'm not familiar with the core CS experience since I don't play it but I see that the game has achieved a whopping 1,000,000 playercount which is quite an amazing feat. If a even a slither of that total playerbase were exposed to custom gamemodes there could be thriving communities globally.
I hear support for community servers is lacking in CS2. Assuming it was as easy as cs:s do you think there is a demand for zombie servers and a potential for a resurgence in players?
