The problem is almost every game on Roblox is social and the matchmaking isn't mature enough to ensure players in a lobby can all communicate.
My favourite is "generic roleplay gaem". The main fun is inciting riots against the leader or forming alliances to do raids. I could join a game and within half-an-hour I'd be engaged in drama, since Roblox incentivizes ephemeral lobbies with random people meaning I don't need a lengthy time commitment to form an alliance.
But I can no longer do that because I am 25 years old and the lobbies are too young. Heck, I'd rather play that game with only other users over 18+ because I could swear and be more toxic. But the matchmaking system literally makes that impossible.
I've had the same Roblox account for 18 years and have spent tens of thousands of Robux on the platform. I let Roblox scan my passport even, so they know who I am. Even though I own nearly 1000 Steam games, Roblox still filled my desire for low-commitment social games I could jump into on my phone or computer if I had a few hours of downtime. Now it is effectively unplayable.
I'm in favour of child safety. But these measures were implemented poorly and needed to be paired with matchmaking to not destroy the platform.
