Ark Survival Evolved.

Waking up on the beach, getting insta-murdered by a raptor.

Managing to meet up with your mates, building a hut, thinking you are doing ok and carno eats you and your hut in the night.

Taming your first T rex, stomping about monching everything, thinking you are doing ok, then suddenly giga eats you and everything you love.

Wish I could recapture that feeling.
