Diablo 4 recently saw a bit of an uptick in its player base with the release of its Vessel of Hatred expansion, which includes the hugely popular Spiritborn class. Unfortunately, some controversy surrounding Vessel of Hatred's story hasn't helped it at all, and Diablo 4 may need a big shot in the arm moving forward, especially in light of another game set to compete with it in December 2024.
The original Path of Exile has been around for over a decade now, so while it might currently have a difficult time pulling players away from Diablo 4, the same might not be true of its sequel, Path of Exile 2. Currently, Path of Exile 2 is set to launch in an early access state on December 6, 2024, which could potentially pull players out of Diablo 4 and into the world of Path of Exile. With its launch window and the fact that it is aiming to be a more accessible experience for newcomers, Path of Exile 2 may eventually prove to have the upper hand, at least for the time being. As such, Diablo 4 will need to do something big to maintain its player base in December 2024.
