I’m not where you have heard the Roblox is attempting to adjust for mature audiences because it has appeared quite differently in recent years.
With the closing of the forums, lack of war-group supports, the in-ability of being able to dev-ex from trading, ever evolving chat filters that tend to block out more and more each update, and rules against “dating and its likeness” and violence restrictions that make games such as the SIMS, Intense war games or something similar an impossibility, ROBLOX definitely trends towards younger audiences.
HOWEVER, I’m not complaining or saying thats wrong. From a developers standpoint, you can probably make more money via DevEx now than every before. Older users or more likely to grind for what they want while younger ones drop cash. It sorta sounds wrong but it’s just factual. I think those common game-types are popular because its what the majority of that age groups is A: Wanting to play, and B: Willing to spend money on.
