ESO doesn't support true cross-play support. In ESO, "cross-play" only works within the same family of consoles, meaning all Xbox consoles share one server and all PlayStation consoles share another. Here's how it all works:
- PC players have their own servers and won't encounter players on any console.
- Xbox players have a server shared between Xbox One, Xbox Series X, and Xbox Series S.
- PlayStation players have a server shared between PS4 and PS5.
- Stadia players share a server with the PC community.
So if you buy ESO gold for PlayStation, the gold will work on PS4 and PS5; if you buy ESO Xbox gold, it works on Xbox One, Xbox Series X, and Xbox Series S.
