Well I'm not making a claim about AAA development here, you are. You said "let's not get into it" and then proceeded to...get into it. It's not common sense that more than half the work is thinking up ideas - I haven't developed AAA games but I have done game development on my own and programming is far from just plugging in ideas, it is much more difficult than coming up with inspiration and ideas. Have you ever tried to code someone else's idea?
I didn't say our posts conflicted. All I asked was where you got the argument that the DLC in CoD requires no work. Your post "I don't like most DLC" and my post "I think people that hate all DLC are silly" are not in conflict at all - you don't hate all DLC, therefore you don't fall into that category. My question was unrelated to that thought, it was related to your own post. Asking for your credentials in making that claim isn't a declaration of war, it's a discussion.
