I agree for the most part about procedural generation.
Though for me it is interesting to see the possibilities, and that is what drives me a bit to explore. Of course things will be similar, I've seen personally some creatures that are similar, plants as well. I've seen other people playing and essentially seeing the same creature but is considered different in the game.
As a programmer, I feel I have extra enjoyment of the PG. What I am wanting to see, how close a planet could be to earth, at least one biome of earth. Or other known planets/moons.
I feel that the only way to make PG work in an artistic sense is to use a neural network of some sort, teaching it what planets look like and what to expect. Basically you'd create every possible variation you'd want to see, training the neural net, then letting it run. You'd further train it, approving and rejecting various iterations.
If anything I think No Man's Sky has shown PG can be used for more mainstream games, so we may see more of it, but hopefully learning from the faults of No Man's Sky.
