games where I can just build a house on the top of a really tall mountain overlooking a valley and fuck off?
I've already played minecraft and ARK, there must be something else

nothing like pic related that i can think of, it's either stand on top of mountain overlooking a valley, or build a house, you don't get both, most crafting games look like ass and don't have good enough world gen for those kind of vistas

nothing like that exists

Valheim, but you'll have to put the work in for it
