It can be a bit overwhelming, yes. I purposely did enough of the main story line in ToTK so that I could get the Hero’s Path and the Travel Medallions. And now I’m ignoring the main story and just exploring the world bit-by-bit, like I did with Breath of the Wild. I’m still thoroughly exploring Central Hyrule. I’m racking up side quests and adventures, but only doing them if I want a break from exploring or want to better my gear or something. It takes the pressure off for me to do it this slow, relaxing way. The game feels like it has hundreds of hours in it, which is what I tell myself when I get antsy. I have almost literally all the time in the world.
Heaven’s Vault was fantastic and can be played multiple times to get different versions of the story. It’s also on sale right now. What I thought was especially well done is how they tied the narrative to replaying aspect.
