I also wanted to ask a smaller question, if there were to be a roleplay server, what would be the best setting in your opinion?
Any role-play server can be successful by convincing it's players to role-play with an engrossing and environmental build.
Meaning, a nice looking build, fitting music to a theme, and interactivity.
As for settings, not sure. That would require brainstorming.
City/Medieval would be easiest with the most support.
