@Aywren Ah, fair enough. Hmmm... I haven't done enough story in TotK to say whether or not finishing the BotW story is required or recommended. But it's a safe bet to say finish BotW first. I think you'll appreciate TotK more.
Since I've been playing TotK a lot, yet haven't done much story, what's the deal? I'm exploring both new and old parts of the game, discovering surprises, and toying with the new crafting abilities! I've only done a few main quests and side quests. The game world is simply a joy to play in.
