I think Roblox can be bad in a "badly moderated online space" and "potentially abusive monetization/exploitative sharing structure" - the game itself feels good?
the tradeoff is with something like godot you only have examples/tutorials and hardly ever something "finished" or "very fun" or "thing people are playing".
something like roblox or another modding-focused game allows you to see what other people did as inspiration or to show what other people are actually interested in, as opposed to just making things for yourself.
