Roblox is terrible.

Well... what is your reasoning?

I don't need reasoning for a fact?

Do I really need to argue about this. You really should have a reason to hate anything.

It has the graphics of a PlayStation 1 game, and it's playerbase reminds me of a preschool. Maybe it's just because I'm 17 that it doesn't appeal to me.

Alright, the player-base and graphics is a reason I can accept. (course, the counter for the graphics is a GPU is not needed for Roblox)

I will say, player base stinks, but Roblox does offer some... advantages... http://blog.roblox.com/2014/03/earn-up-to-10000month-making-games-on-roblox/
