The game is really well done. It's solid. However I wouldn't say it is strategy, but a "tactical" game with a lot of luck.
The game, basically, consists into connecting planets which needs resources. When you expand, you discover new planets, which may have the resource you need or not. Also, you have some research, but the most of it doesn't seems useful. There is a campaign with some special rules too, which unlocks other game modes with extra difficulty added.
You cannot have a long term strategy in this game. You only adapt to the RNG, but frecuently, it becomes unmanageable and you need to look for another direction to expand your empire.
That wouldn't be bad if you were trying to "win" against a rival. But this isn't that kind of game. It's a score based game, and if you consider "to win" reach 5 stars in each random map, after 35 hours of game I may tell you that some maps are simply impossible, you will never get that score. In other words: the RNG disables you from "winning" every map.
After these game hours, I'm a bit bored because I know that I don't achieve max score due to bad luck, even playing safe, but had some nice moments.
