It would be awesome if players could create things in game, and now that you said, i'm pretty sure there will be people to make some really cool mods for the PC version. I wish they improve the game based on the feedback after release, tho i don't think it can get any better on consoles, they might as well add some new content like, new graphical elements, better multiplayer, some quests like, hunting or traveling to an unkown planet to fight a boss or something, i don't know, something to actually keep you playing, but i think when Youtubers stop making lives about it, like "Look at this awesome new planet i found" will be the time they will just give up and stop updating the game. If they just keep the game like it is now, it will get boring soon.
