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.

The “How to Train Your Dragon” game on Roblox has more than 28 million visits. Over the weekend, the movie raked in $83.7 million in ticket sales in the U.S. and Canada, surpassing expectations.

Do Big has been scooping up other titles, including Roblox’s biggest hit ever. In May, the company bought a stake in Grow a Garden, currently the most popular game on Roblox, for an undisclosed sum.
