What are the main features you would like to see in  a Realm or Server?  

Would it be Survival worlds, and a survival community? Would it be built upon voluntarity and community builds, or shops to buy stuff?   Would it have a village of the users, or large separate plots somewhere?  What would be your dream realm/survival world server features?

Would you want to have PvP's arenas? Or Skywar areas?  Other games? Roleplay?

In short what would your favorite Realm include of features and stuff! What would you as a player like to make you stick around and contribute to the Realm?

Note: I'm explicitly not asking for features on a server (with limited Survival options, or pure Creative builds), which could be it's own thread.
