Since Roblox is not even trying to pretend to care about their user's safety anymore, how about we make our own game platform/engine?
It would basically be a website similar to those 2000's/2010's games catalogue websites that is directly connected to a game engine so that users can make their own game and customize their avatars.
(yes basically Roblox but without the money-hungry, preds-protector CEO and a different aesthetic)
It's not impossible but it would be eaiser to make as a team than if it was only one person making it.
