I know I have been back and forth with game engines but i just don't want to create a point of no return. But it seems when choosing, I went in a roundabout way of sorting needs, and which is my favorite. I've used Gamemaker since it was Gamemaker 5. But I am no longer a beginner. So, one of the things that help me choose during pre-production, is ease of use, convenance, and style. Unreal was hard but a good engine. But I need 2D and 3D. I always go in a circle and wind up at Unity. It is my favorite. I have chosen! So, more prototyping and full-fledged production will happen very soon.
