I don't think piracy has much to do with it. AAA (of even AA) single player games sell really well. Just not well enough to be the equivalent of a money-printing machine like Fortnite. Spiderman 2 sold something like 17 million copies between PC and PS5. Still nothing compared to the $30+ billion in revenue that Fortnite has generated so far. So everyone is chasing that Fortnite $$$.
