Echoing this Lee, it's an absurd idea to expect servers to be capable of millions of players, even if you look at Counter Strike on PC which has a sizeable following it doesn't hit 1 million players. Considering the first helldivers was nowhere near as popular it's hard to predict this would have gone down as well as it has. Sony could easily spend a fortune now ramping up servers similar to Palworld but is that practical? The numbers will drop fairly quickly with quite a few online games coming out over the next month or so.
