That only tells you which mythology of monsters to expect, most of Viking life was farming and hanging out just like any other settled culture.

While the expected game loop is gearing up to fight the bosses in order to unlock tech upgrades, it's surprising how far you can actually progress without doing that if you want. You're also free to have separate combat and building worlds and transfer tech from one to the other.
