In its early access state, Gadgeteer is both a fantastic Rube Goldberg-style reaction machine builder and, at its most gripping moments, a true example of VR Presence—where the act of building and testing a machine becomes so engaging that you forget you’re playing with code instead of physical toy dominos. The collider occlusion bug within the physics system should still be addressed, and continued improvements toward the locomotion system would be nice. But, content-wise, Gadgeteer is already a complete package out of the box. At $15, I consider it a steal.
