Better Alternatives To Message Service or Memory Store Service?

I’m creating a plane game and each person is going to be in their own server however I still want people to be able to see other planes. I have tried using message service and memory store service but they both have limits which results in it failing after a while. Do you have any ideas on any other services that I could use to achieve this or a better way to achieve this without hitting the limit?

I think this is just a terrible idea overall. There’s a reason every multiplayer game doesn’t do this.

it would be but my idea is to create custom servers so that there isn’t a crazy amount of lag. Also the reason i need to do this is to fix floating point
