100% agree. I don’t know why you were downvoted. I assume that some people hate it when you dare to talk reality. I have run my own successful game biz for 5+ years and have written more than one commercial game engine that was used to release commercial games on consoles and PC. And I 100% agree with you. Unity (for example) will make you at least 10 times more productive than writing a 3D engine from scratch.
