I think I put 50-60 hours into it. I mean, I had a bitchin' ship in 1.0. And I had all the good stuff. And then 1.1 came out and it's like "hey guess what! You have to do a whole bunch of bullshit because we completely changed things and you will never get a ship as bitchin' as the one you have ever again. Unless of course you're willing to sit there and farm for 60 hours."
But then, No Man's Sky's raison d'etre is "try to make a boring thing interesting through grandiosity."
