TBH my biggest problem with NMS is that the generation isn't as great as it looks. I only care about exploring planets--anything else, I'd go play EVE or Elite. The planets suck. They all have the same robot enemies and natural predators are laughably easy to fry even with the starter gun. Every single planet is covered in little bases (I thought I was discovering them?) and while the planets and and animals seem to change, all bases look the same. Why wouldn't they make the bases automatically generate with a series of styles? That would be cool.
Also, the planets are all 1-biome. It's a desert planet, a snow planet, or something inbetween. There's no Earth-likes or biomes with multiple biomes. The animals look stupid because the generation that designs them is totally random, but I'll let that go because it can get pretty funny. Also, it doesn't help me feel immersed when I literally can't fly my own ship or go below cloud height--you just point at a spot to land and hit a button. The ship automatically lands for you. You also auto-land in shuttles. Hard landings on Elite are pretty fun, and IDK why they'd take the ability to crash out of the game.
Even if the generation was truly breathtaking, it would get old eventually. There are no fun incentives to visit planets. It's either a boring fetchquest for a linear story (the point of this game was to write your own story!) or you are literally just mining. Instead of exploring planets I would tend to just scan for resources and spend the next few minutes grinding down a pillar of rocks in a very boring fashion. My suggestion would be to totally remove mining from the game--it's boring as hell. Maybe keep precious minerals in small forms or something. Also, survival boiling down to 'FIND CARBON!' isn't very fun. Especially when every planet carries the essential elements for survival. It's just scanning and then jetpacking into the distance. The new toolbar that let you call your ship to your location was a good idea, though. Base building looks really cool--but it's an exploration game, so I'd feel tied down. Purchasing mobile fleets was a much better idea.
btw, get the 3rd person flight mod. it feels awesome.
