Nicholas Francis, co-founder of Unity, has left the company to make his own games.
Writing on the official blog, Francis said he'd come to the realisation that after years of supporting the tech behind the firm's engine, it was time for him to finally get creative with his own projects.
"I will be leaving Unity in order to join your ranks and dedicate myself to creating games," he wrote. "This has not been an easy choice - in fact, it has been one of the hardest ones in my life.
"Over the years it has been amazing to watch Unity getting better and better at such a crazy speed. Lately I have been incredibly inspired by what you guys have been creating and have been experimenting more and more with my own ideas. It's made me realize that I have games I want, no need, to make.
"As great as it has been building Unity, I have come to feel that actually using it is what really scratches my itch. On days where I can just get into the zone and fidget around with some shaders, gamecode, a custom editor tool or whatnot, I feel really fulfilled. And at the end of the day, that's what it boils down to."
