Obviously, Roblox is a platform for ages 12+, I suggest this game is an average of 10+. Although there can be some sexuality and hate towards newer players and/or furries and minorities, it's a fairly decent game. It's all community made, (yes, that can include pronography but it usually gets deleted.) You can make your own world via roblox studio, hoping none of the models give you a virus. Let's go over some negatives, shall we?
OHHHH boy where to start?
Roblox can be fun, but it is like a pay to win type game. Unlike other popular games, which aren't pay to win, Roblox seems negative towards smaller children. (I am being completely bias there) and then there's the controversial updates... I'm not going to mention those as I'm pretty sure 80% of people have seen those in your youtube recommendations or subscription notifications. There are also trollers, like Albert/Flamingo, but the chances of you being in a game with a media troller is near 0, and a non-famous troller is pretty much a 1/25,000, based on the amount of times I've personally encountered one.
