I hope you are right - I'm finishing the Demo project now. But going too fast doesn't seem a good way when software needs more work. My project is over 2GB and when you do something complex with thousands objects and a very complicated logic, you see all what should be improved in Unity 3D. All weak points are visible. I write all the comments not because I don't like Unity, but because there's a strong pressure on me to make a complex project that will be working without problems. I must overcome difficulties and limits.
