In a world of underdeveloped, overreaching, open-world nonsense games, it is so nice to play something polished that actually ends AND satisfies.
Don't listen to the negative reviews, this game is super fun even though it's short. Disagree that it is anything like Subnautica, besides the fact that you are dropped on an uncharted alien world.
My first playthrough was co-op. I'm looking forward to running through again solo. 100% recommend for real gamers, not fornite or cell-phone people.
