Also, if plex goes down so does your server. I love plex but if any of the 100% self hosted stuff catches up I’m absolutely jumping ship.
That’s only for authentication and some apps. You can set an IP whitelist so it doesn’t require auth from certain ranges - when I changed ISP a little while ago, I was still using Plex offline.
Unless you’re a game by Bethesda, most people (and most reviewers) are going to assess you at release. If the release is shit, they’re going to stop playing and forget about the game. A patch 12 weeks later won’t help, because everyone has moved on.
