I've only played about 2 hours of New Vegas before ragequitting but I still love Fallout Shelterhttps://www.skial.com/threads/fallout-shelter.60149/
I haven't, not much of a fallout fan so this didn't interest me.
Money is pretty slow at first, but once you get to 50+ people in a vault or two and get the hang of it it gets a lot easier to start new vaultsIt's hard getting things going.
