I keep thinking about having a map. Have 3 Factions and make them fight over a daily Real Time Strategy World Map.
Each Day 3 factions conquer one city, getting closer to the capital until it's conquered. Have a day of rest and a new map begins.
Think Risk.
Unfortunately my idea will not work as it's basically who has the most higher level TownHall bullies win.
But it's so fun to go on the forums and rally support to invade/defend the capital. If you're the 3rd faction on the outside looking in, it's not as fun but I always liked Real Time Strategy Maps and it works well on any PvP game.
