Oh, man, that is a magnificient time-waster called "Rust".
I`m so jealous to those guys who invented the game - they already sold 1 million copies+ (12 US Dollars each through "Steam") and the game itself hasn`t even been released yet - you play some raw alfa-version with regular updates.
Survival RPG with lots of in-game conversations. Reminds "DayZ" a lot.
Make a fire! Do crafting. Cook some food. Build a castle! Defend yourself from enemies! Do barbarian raids on "friends"
P.S. New video every Thursday.
