It’s no secret at this point, that despite No Man’s Sky being an absolutely incredible achievement for the small team at No Man’s Sky, Sean Murray definitely said and showed quite a lot along the course of development that changed quite significantly or just simply never made it into the game.
The No Man’s Sky Reddit have taken it upon themselves to compile everything that is missing from the game, that was spoken about on the marketing trail, right up to the trailers that were used to promote the game at launch. After all, we’re still not even sure that multiplayer exists in ANY form.
I’ve listed some of the larger mechanics that are flat out not in the final version of the game:
The loss of planetary physics, which were said to govern many different systems, seemingly in a cascading effect from the top down: | 1234
The retooling of ships to make them all functionally identical, rather than having different classes for different playstyles, essentially homogenizing ship play into a single playstyle: 123
The reworking of factions from something with broader significance, into the very simplistic system we have now: 12
Resource distribution following none of the rules that were spoken of, instead resource variety is more shallow than we’d been lead to believe, so distribution was seemingly homogenized regardless of planet-based factors (likely an effect of the loss of planetary physics)1234 || This also had a knock-on effect for trading, which was trivialized by the ease in which most resources could be found: 123, and also crafting, which went from something Sean hoped would be community drive a la Minecraft (likely because there were far more resources originally, a la Minecraft, there’s more evidence of this than just the crafting,) to something that could only be done through recipes the game must teach you before you can actually use: 1
