Global game servers variable

Is there a way to store a variable that’s the same across all servers and is updated live?

Like say there’s a value of 100 and someone in 1 server takes 10 away and someone in another server takes 10 away as well and for both of those people on separate servers it shows up as 80.

Please tell me if there is a way to do this, I’m pretty sure there is.

There is not. The closest you can get is MessagingService to communicate between all servers of all places of an experience or DataStores. MessagingService is best-delivery and DataStores have rate limits, so neither has the resolution you’re looking for.
