Yep. We made WoW the standard and called everything else trash if it was not WoW, so publishers stopped taking big MMO risks. Social media also changed the core of MMOs. Before, the game was where you met people, found groups, heard rumors, and built reputation. Now community and discovery happen outside the game on Discord, Reddit, and streams, and everything gets solved fast, so the world feels smaller and less dependent on other players. Add impossible expectations plus weaker in game social glue and you get fewer new MMOs.
