The UI is, and you should buy it just so you can complain to other devs about how a UI should be done. Because ES fucking nailed the UI. There are still issues with the strat map being a low information content wasteland, but the rest of the UI is just phenomenal. As far as the game itself, eh, it's pretty rote space 4x. They do a few unconventional things but nothing worth remembering at the end of the day beyond the UI.
