Roblox sex games are commonly referred to on the platform as "condos". They're spaces, generated by users, where people can talk about sex - and where their avatars can have virtual sex.

In just under two months, a Roblox user-created game called Grow a Garden has become a massive hit.

Grow a Garden has released its Summer update 1.11.0, propelling the Roblox game to comfortably the highest recorded concurrent player count in video game history. Check out the update 1.11.0 patch ...

Following the launch of its 1.07.0 update, Grow a Garden had nearly eight million active players, which is more than the top 100 Steam games combined.

Like YouTube, Roblox started as an online stage for young creators. As the company grows toward 100 million active daily users, contributors are making big money selling games.
