Explanation:

I am in favor of separate servers so that people under 18 can also play the game, because I find it absolutely bad that all my progress in the game is lost. The principle is also simple: just create a UI where you can join separate servers that only have a certain age group (the age groups specified by Roblox). A simple sorting system.

Safety:

There can also be no abuse because if older players joined a younger players' server, they wouldn’t be able to chat anyway.

Win-Win:

I think this is also good for your profit since the game would get more players again, and this community would grow better and further.
