Okay so it's not Skyrim in Space MMO. Besides that, what is wrong with the game?
The constant lies/false promises from the developer which only fueled the completely unrealistic levels of hype, and which resulted in the massive gap between what was promised and what the finished game looks like. IMO the worst lie was during the E3 2015 presentation where he pretended what he was showing was something picked at random and therefore indicative of actual gameplay, whereas it turns out it was entirely scripted (which was only discovered after the PC build was data mined upon release).
Leaving aside all the bugs/glitches/crashes etc, the game itself is kinda boring and repetitive, the planet textures are dated and the AI is terrible. It's also ridiculously overpriced for what is essentially an (unfinished) indie game. I didn't buy into the hype seeing as a) it's a small development team, and b) all games companies lie, but I expected more than that. I played it for a couple of hours and got a refund.
