Survival builder

* Frostpunk
* Oxygen : First Breath is a free to play version of the main game Oxygen. This version has the first 50 in game days available to play, which is roughly around 3 hours or so of gameplay depending on your speed of playthrough.
* There were billions
* Endzone | In 2021, a global ecological disaster plunged the world into chaos and brought humanity to the verge of extinction. Only few were able to escape into underground facilities called "Endzones". 
* Against the storm | Unlike most survival city builders where your focus is on a single city, in Against the Storm you must build a vast, prosperous network of settlements populated by diverse fantasy races, each with their own specializations and needs.
*Timberborn | You manage a settlement of post-apocalyptic beavers, which are trying to carve out a living on a riverside which periodically drys out
*Banished | very similar feel with the constant struggle for resources and worrying about the weather, :)
*Cliff Empire | It's a great relaxing city builder that still has the excitement of tower defense against occasional attackers. Worth the price, especially when on sale. Has a relaxing but engaging atmosphere and interesting aesthetics.
*Iron Harvest | goofy dieselpunk rts set around the time of the first world war technologically speaking except with mechs, what's not to love. Features a fleshed out campaign
