Are you serious? that is business. to make a better product then your competition. there is nothing wrong with making a product just as good at a more reasonable price. I have idea what type of business ethics go on at Epic but you did just that to unity and cryengine. it is crazy for the company you work for to do what you are claiming is unethical. there is nothing at all unethical about creative a competitive project. especially in a competitive market.
