Greetings. In my opinion, games where it's hard to build something last much longer than you think, because people measure the cost of time and value their effort, so don't let it get lost that easy. The game is interesting for everything you mention in your post, open the spirit of human exploration and that hooks you into the game, you want to grow your mines and amount of resources to take that step and explore the galaxy did you see the new map, this spectacular. Although I'm just starting I really liked the game.
