Licenses and middleware can be chosen more proactively to preserve and distribute the server if they know during development that it’s a requirement. There are tons of people who functionally play MMOs single player already, when the server is already running. And I play a 12 year old fighting game that’s easily able to coordinate 20-100 people to play it multiple times per week with nothing but Discord; there’s no doubt in my mind you’d be able to get 40 people together for a raid on a private server.
