@LukeAlmighty Roblox is a tad more complex.
It is a website where you create and play games.
The game's webclient comes with another software that lets you create videogames that you can then host on the platform, sometimes even make money off it (though Roblox takes a cut of the revenue if your game has any form of monetization).
Not only that, you can also submit and use various resources, virtual customization items and more trough the online shop.
The unique thing about this game is that you need not download anything else to play, just the webclient launcher.
The Metaverse I have no fucking clue what it does but it's probably some gay uninnovative and boring piece a shit software that people inevitably use to try and scam the twelve idiots who use it unironically.
