Well almost simillar age as you are. If you're really bored, then It's fun. But I still enjoy playing it too.
I like playing Roblox if i'm bored and I have nothing to play :P
welp im too very "old" to play roblox too, but i enjoy it nevertheless, more as a developer than just playing games :| . Also, Roblox is changing pretty fast right now, so it will be pretty common in the future to see older masses, for the Engine is getting better and so are the developers (take Room 2 and Mad City as examples)
I think it's a nice game to play alone, or with your friends. You can also make friends. It has it's ups and downs, but overall it's a nice game.
we're actually on same age and that not a reason that we should stop playing what we like, they are not the one should dictate what we should and should not to do in our life.JUST STAY WHAT YOU ARE BRO, THAT'S YOU LIFE

note: I am not a 10 year old. I am 21 years old, but I really enjoy playing ROBLOX. Normally people of my age are doing CS GO, COD, or GTA. But I still play ROBLOX, people on discord say that I am acting like I'm 10 and stuff and I really don't like that. What is your opinion on playing ROBLOX at my age?
