City Builder Template [Blueprints]

One more question…I was hoping to use this template as foundation to create a multi-player, turn based game. I quickly added host/join functionality to the main menu. But digging in to the player controller code, it looks like everything hinges on the “Singleton” object. Would it be a complete rework of the code to add multi-player LAN functionality? (I noticed a “City-Networked” map in the folder structure, but it doesn’t appear to do much)
