Oh yeah I forgot I'm not allowed to curse on a public forum without people thinking I'm ragingly angry
You can get thousands of hours out of literally any game if you love it enough, but other people will put far less hours in at the same time. It depends on the person. If you previously put thousands of hours into other open world games then maybe but no one can tell you whether or not you will. Either way in my opinion you should only at most expect an hour per dollar spent on a game. I got 105 hours out of botw and I'm pleasantly surprised how much I got out of $60. But I won't force myself to play it after putting so much time into it. And again, single player games can't be dead, that doesn't make sense. You play it and enjoy it independent of other people.
