What is this game actually?

Can somebody tell me how this works?

It's kind of like role playing. Think of what would happen if you had put Pokemon in an open world setting in 3d. Or a visual version of Discord where you can actually see the action instead of just typing it.

Roblox is an MMO game with multiple games in it, with different variety of avatars to choose from and some toxic players on the way but anyways its fun if you appreciate it

It's basically a game with a bunch of people on it who make games, clothes, groups and more. You can customise your avatar, play the games on Roblox and sometimes even make games yourself. There's also a currency on Roblox called 'Robux' which you can buy for real life money so you can customise your avatar, play games, make groups, etc. Overall great game, the community can be fun too, I recommend it :]

It's a platform with games meant for kids in general they try to hit a younger audience but still can be played by a grown community
