If you’re happy to pay whatever it costs to host then there’s no other disadvantage to this.
The only thing I can think of is if you somehow end up at odds with an admin of a big instance and they defederate your instance. Or perhaps in the future major instances decide to only federate with instances of a certain size, for some as of now unpredictable reason
It’s the question.
Lately I’ve been thinking about how you’d design a racing sim that rewards and gamifies clean racing but the basic answer is that you’d have to set it in world so different from our autoracing history and technology that you’d lose 75% of your player base who are mostly interested in real cars (the same way FIFA games appeal to people who want the real players, and don’t actually care about the game design of football).
On PS5 there’s platform native ‘Accolades’ where you can rate the people you’ve played with, but Bruce I never play the kinds of games that they’re designed for I have no idea if they’re used or how they even work. The point being though even Sony were trying to approach this topic at an OS/ecosystem level.
