Some good survival and or crafting games?

Kinda like minecraft and trove and The forest and and 7 days to die

problem: has to be either cheap or free
and 20 isn't cheap for me… : T

FarCry 3 - Awesome game…

If you can't afford $20, maybe you should figure out how to pirate games. Hint hint "Youtube is your friend."

Rust

Rust, but it's so broken right now that you might as well just wait. There's also H1Z1 coming out that is going to be f2p but you can pay for early access of the game.
