cross server communication thing

i could make a horror sandbox game out of this if this would become a real game one day it would be entirely focused on databases, needing to transmit data constently to stay alive and such mabye, needing one player another to co operate if they want to survive, communicating server to server, who knows, a creature travaling server to server, ending those who are unfortinate, as you see a green box flashing turning into red right next to yours, completly unready and unexpectedly, you knew you had low chances, very low. i know i could ve used MessagingServer or profilService, i could mix with that too, but the concept of needing to transmit data constently to survive not only that with a limit needing to be careful which data is worth it reading and writing, sure i could fake it, but having a real limit just makes it (for me) cooler i guess.
