A bit of programming is all that’s needed. If you’re using ER then you can save the version on the server and the only coding is client side.
In the client side, you need to code a version into it and if the version is the same as the server’s (this can be found in the sub that sends the version and server online status, just looks for the label on the menu) then it lets the player log in, otherwise have the code say enable = false for the buttons and the message displayed just has to say “Please update to the latest version of the game”
If you’re not using ER then you have to have to program the version into the server as well and send it to the client.
