Nomadic accurately and succinctly translates the experience of those early days No Man's Sky: of wandering strange worlds and harvesting resources, struggling to survive and thrive in a hostile environment. The Breathless system is simple, clear, evocative, and brilliant, and it adapts well to a solo, semi-journaling experience. 

You can knock out a planet in about 40 minutes or so (give or take) and move on to the next adventure, changing things up dramatically. 

The game provides everything you need for wonder and adventure, though I also find this a great game to toss in other Sci-Fi generators and oracles to keep yourself surprised by the discoveries ahead.
