Grey's Murder is an interesting little game on Roblox where players assume different roles and must fulfill them throughout the match.

The video game was just valued at a staggering $45 billion. It's also been a lifeline for my children since the start of lockdown.

Roblox is lucrative too: any person who creates a game within the app can charge people real money to play it. The company claims that some of its top earners can make as much as $250,000 every year.
