I've heard how worst is this game was since they did not do as what they've promised at all, and the game was completely empty. It was crowned "No Man's Lies" and rightly so. Nevertheless, the developer didn't just take all the money and run, but what they did is commenced to fixing, improving and keep working on it.

Until now, after update by update this game has made a huge improvement, it's all that was promised and so much more. There are an infinite universe, million planets to explore, and tons of stuff to do such as Base building, Ship battles, Resource Gathering, Outfit changing, Weapon/Exosuit/Starship Modifying, ETC.
Also you can Co-op with your friends (up to 4 players) as well.

I would extremely recommend No Man's Sky. This game is literally epic and amazing, Worth the money at all. I truly appreciate Hello Games for made one of the best creative game for everyone.
