Its not said that they need devs to target home machines, it says they need to give the resources so people can host it themselves, period.
Also, tell me you’ve never worked with scalable infrastructure without telling me you have never worked with it.
There are dozens, if not hundreds of games, including MMOs, that are privated hosted, and by that I don’t mean hosted in a basement potato.
Look at Ragnarok servers, there are hundreds of them, DEDICATED servers, with all the newest technology, for an old game nonetheless.
Have you ever seem how massive the infrastructure are for those big minecraft multi-servers? Thousands and thousands of concurrent players.
Im not asking you to research what you’re talking about or anything, but if you clearly dont know what you’re talking about, refrain from sharing your opinion so you may not negatively influence a similar minded person.
