alt Hacker News> Peer to Peer games with no central authority would be so rife with cheating that you’d only ever want to play with friends, not strangers. That sucks!
Back in the the day RtCW had a server anyone could run and you could give out the address:
* https://en.wikipedia.org/wiki/Return_to_Castle_Wolfenstein
There was a server that a ISP / cable company in the southern US ran that I participate in and it was a great community with many regulars.
P2P can be awesome with the right peers.
If you can run your own server then that's still a central server. That still lets a community of people work with a central authority. It's just a different authority from the game's publisher.
