NMS had one of the most misleading and smart marketings I have ever seen, very few knew what the game was about yet many wanted it, it was a masterclass of empty hype, a pretty popular practice for certain companies this days, is very effective to have the people hyped for something for years even if the product is a piece of garbage, but during all those years they were trusting you, and talking good things about you, and buying your products. The hype is money.
And yes, the actual game looks far worse than those trailers.
