They're all pretty overused and trust me, there are plenty of servers out there with these gamemodes, and you adding another one to that list is useless.

World War Roleplay? That's the only thing here that isn't overused but I doubt it would get any players anyway.
What would you do there anyway? Join the army and go shoot people? I'm sure that wouldn't even be roleplayed and it would just turn out as a massive DM fest.

TLDR none of them.
