That all sounds great to me! I mean I certainly don't have better ideas.
I know biomes were mentioned as a hint to finding resources (so, whole planets then?), and it was also said that the starter world is missing some resources. I know that was all said, but I still want to say that I think it's very important that not all reosurces are found on all planets. Something that murders No Man's Sky's variety is that the same resources are found in the same form on every planet. When this is done, it really makes it hard to convince your brain that a planet is unique. As such, I am suggesting that you really ensure that simply the locations of these resources are diverse, especially on a planet-to-planet basis. It will make searching for them far more interesting and rewarding.
