I want to see more servers with passionate owners that are genuinely passionate about the gamemode they're hosting. It's pointless to host a gamemode that you don't enjoy playing because unless you play your own gamemodes and become a player of your own gamemodes yourself, you'll never really know what is fun and what isn't from experience.
The idea of coming here on Facepunch and asking, "Hey guys, what gamemodes do you want to see?" is completely wrong. It means you're aiming solely for popularity. That's not how you'll get popular. Popular servers are a consequence of high quality servers. High quality servers, on Garry's Mod, are a consequence of high quality and fun gamemodes. High quality and fun gamemodes are a consequence of a developer/owner who actually enjoys this gamemode and keeps playing it and improving where he finds flaws or potential for improvement.
Once that's done, you'll always find someone to play your servers, regardless of the gamemode.
So when you come here to ask us what gamemodes we want to see, here's what I'll answer; what gamemode do YOU want to see? Got the answer? Good, now go do it.
I made this thread to see what the gamemode is in high demand. Not to be popular
