How about turning FOS into competative multiplayer empire building game?
I mean kind of empire building game like Settlers series or Anno series (from Ubisoft). Vault is something similar to medieval castle. Self contained resource/space/population limited community for defense and production with occasional trade and war.
The raiders are actually dispatched team from other vault. The radio studio and high happiness will attract dwellers from other vaults. Each vaults will compete for resource and talented dwellers. Happy dweller will pay tax. It is source of vault revenue.
Vaults can trade extra power food and water ( and dwellers or baby too) with other vault using delivery team and truck. It can be hijacked by raiders too. Each vault can produce some luxury commoditis to earn more CAPs.
It will be some cross between mobile farm management game and warring game. (Hay Day + Clash of Clans) It will have much less war and combat tactics aspects than CoC but more community oriented and have strong management and trade aspects. War will be very expensive option in terms of CAP and dweller population..
I am playing both CoC and Hay Day. and I am bored of endless war of CoC and endless peace of Hay day. I think that Fallout themed mobile game can break such mold and make a game that has both war and peace in a game.
