They definitely deserve to release something that players can purchase at this point. Some suit designs, starship skins, something. They’ve given out 27 free feature updates, many that could have been paid DLC.
I’ve heard many times from the No Man’s Sky community on Reddit that has stuck with them for so long actually want to pay them for the immense work they’ve done over the years.
Yes, I am one that would gladily pay for a DLC. Honestly though I don’t know what they can add as DLC to make it worth and exclusive, at least on the PC where there is mods and save editor to add whatever you want.
Maybe some sort of remastered game with better planet/flora/fauna generation, but it seems to be difficult while keeping all the gamers in the same universe.
