I've browsed through a lot of the Playfab community and have seen numerous mentions of the multiplayer servers feature not being designed to support non-sessioned instances (for example, an open world MMO-style server).
What exactly are the limitations when it comes to keeping servers running for days on end? What are some of the specific challenges and/or barriers that prevent Playfab Multiplayer Servers from being a good option for open-world MMO server hosting? As an example, I'm thinking about games like World of Warcraft and Guild Wars 2.
Are there any other large-scale persistent server frameworks that you would recommend using alongside Playfab, that could specifically resolve this conflict?
Any answers are welcome. Thanks!
