Roblox is a great platform where you can play all kinds of genres of games made by the community from Roleplay to FPS or even strategy. Although it has quite strict rules on what you can upload, say and do this is to keep it safe for it's main audience, younger children.
No matter what genre of gaming you're into, Roblox has something that you'll enjoy which is what makes it so special, and it only takes seconds to load into a game and start the fun. Yes, the main target audience is younger children, but pretty much anyone at any age who is into gaming can find some games they enjoy on the platform.
Another part of what makes Roblox so special is the fact that players can create their own games! On top of that, revenue earned from those games can be exchanged for real life currency - I myself own a game and have made £1700 and 700k Robux (the currency used in Roblox) off of my game, which is pretty amazing.
I won't pretend like it's easy to create a successful game on Roblox that earns you money, of course. Just like creating any game, you need to spend days planning and months developing it, not to mention hiring people for graphic design for your thumbnails etc, so it's not for everyone, but it's still something to think about if you're familiar with the LUA scripting language and know your way around the Roblox Studio.
I've seen a lot of people complain about how Roblox is unsafe for children because of online predators or other inappropriate content. As with all multiplayer games, there is always the chance, no-matter how small, that someone could expose a younger child to more adult content. However, with the right privacy settings and a child that knows what they're doing when it comes to talking with others online, you can pretty much eliminate any chance of this happening.
Thanks for getting through my review!
I hope you found it interesting, peace out.
