I bought Valheim a month after its release in Early Access. I have played it nearly every day since and have only experienced short bouts of burn-out.

I suspect I have avoided the exploration boondoggle by exploring only when necessary for progression. If I have beaten all the current bosses, I will start over with a new viking on a new world. I will also start over if I haven't beaten all the bosses but have managed to screw a play-through royally. An added advantage is since I don't go sightseeing just to be sightseeing, I keep the discovery and spoiling of undeveloped, placeholder biomes to a minimum.

This may not work for anyone else but it works for me.
