I got this on steep sale, and I'm kind of glad I did. The scenery is really pretty, but the flying mechanic's a bit hard to get used to. It could use more in-game guidance to help the player along but, hey, I guess it /is/ billed as an exploration and slower paced discovery game. It really is on you to push on and (often accidentally) advance the plot.

The base game on its own is great fun, but this expansion adds a whole other level of replayability to the game it didn't have before. Megastructures! Megastructures!!
