Of all the projects I have worked on I am always the proudest of the 3D ones. I love the amount of interactions provided by a 3D workspace and the complexity of the physics and objects rendered in a 3D space. I use Unity3D Free for everything I have made thus far and I feel that for my endeavors it is just fine. I hope you enjoy perusing and playing my games as much as I did making them.
