The recently revealed State of Play showstopper God of War Laufey is the upcoming third game in Sony Santa Monica's Norse Era, serving not as a prequel but as a continuation of the saga running in tandem with the first game, and PlayStation is handing out the green light to play Laufey without knowing anything about its predecessors.
Obviously, PlayStation is the expert on its own games – and has a commercial interest in making its new releases look approachable – but I'm gonna go ahead and say you should probably disregard its guidance here and just play 2018 God of War and God of War Ragnarok before Laufey.
