I've tried to get into No Man's Sky on and off for 2 years, and I have just torn myself away from 3 straight hours of what I first mistakenly thought was merely a satire of the former. I was laughingly grateful at the simplicity of the resource system, and relieved at the lack of barrier to entry in the form of loading, tutorials, and handholding, and was soon chasing after a runaway jet engine on a plank. I later thrust myself upward to see how far I could reach without oxygen, surprised to see that there were details beyond this world. I've now visited each available planet. In such a simple environment, I've experienced several memorable moments of discovery.
Thanks.
