"So I will be leaving Unity in order to join your ranks and dedicate myself to creating games," Francis writes on the Unity site. Francis says that in more recent time he's actually felt more fulfilled when creating things in Unity, rather than working on the engine itself. "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."
Francis has yet to reveal what his new project is, whether he'll found a studio or, well, anything about what he's up to, really. But we're almost positive it'll be a mobile game ... running on the Unity engine.
