Well man, yes go back to kingdoms and collect moons. Try to find/get the collectibles, do your best etc... As you like. It's a collect-a-thon videogame and you'll get more hours for your money and such. I just got Zelda BOTW and it's awesome, love the start to it. I've started both SMO+ZBOTW and theyre both amazing/awesome videogames, high quality games and so fun. So cool. They're simply gem games, like precious gems.
