Can you play between Xbox and PC versions on Xbox Game Pass?
Cross-Platform Compatibility on Xbox Game Pass doesn't allow playing between Xbox and PC versions. Differences in content, like the number of islands and special zones, make cross-play impossible. Despite speculation about the Microsoft Store version enabling this feature, it's not the case.
