In honor of Ready Player Two, Roblox is launching a themed treasure hunt with seven user-generated games inside the Roblox platform.

Roblox presents itself to parents as a safe space for kids. Behind the scenes, it's waging a technological shadow war against condo games: digital sex parties where kids are flirting with danger.

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.
