re: Any games like Fallout 4?

Have you tried Subnautica yet? It's a story-driven first person survival game where your spaceship crashes on an alien world and you need to explore, collect resources, and build underwater bases and equipment to survive.

I love Stardew Valley and think it's a great game, but it's very different than Fallout in both tone and presentation. Having said that, there is something fun and charming about taming a plot of land, building the most efficient farm, and getting to know the towns people. It might scratch the same itch for you.
