Steam just released early access game called Subsistence. It is like Rust or Minecraft and other alternatives, but it looks very good so i decided to buy few early access keys and give them here in my site. Here is info of the game.
"Subsistence is a sandbox, first person, open-world survival game (currently only singleplayer, with multiplayer in development). Struggle to build a base and gear-up in the hostile environment. Defend yourself from wildlife and AI hunters (who also build bases in the world)."
So that is why i like it. Sandbox, FPS, Open World, Surviving. I just love all those categories. And when they are all in same game, it must be awesome.
