Don't look to what's successful these days. Look further and make it unique! Create a new game mode as it doesn't have to be the same modes (Roleplay//TDM//Zombies//etc) everywhere.Not to mention people who create new ideas are the successful ones just because they come up with a new dazzling thing which attracts players attention like a magnet and so you could be one of them, if you didn't copy what's successful.Be creative!
I have my own game mode in my mind but still I'm searching for my team.

Good luck buddy!
