I think No Man's Sky come a long way. It's still not the perfect game in any sense, there are still some glitches and it's still a little repetitive, and it could be a little boring for people who are looking for action, but when I saw how much Hello Games put effort to repair game and add so many new things to it, I need to say this. It's completely different games from its beginning stage, it's more complex, and it could be pretty fun for you. So I can say that it's worth to buy.
