I got all the shrines and all light roots. Then I started messing around with building combat vehicles to mess with bokoblins. I’m not a big side quester or story liner, so I haven’t done a lot of them.
I got bored at some point since the objectives were completed. It’s sad, but a game is over when it’s over. While it’s possible to continue through speed running or going real 100%, it’s fine to just be done and move on to another game.
