Another point that could be made is that all the questions in the first part are important and need to be answered, and all the answers in the second part are what the relevant people involved will actually do, but if you add up all the answers in the second part, you haven't actually answered most of the questions in the first part. And I'd say I've definitely played games where major systems were done that way; someone up on high said the system needed to exist, and then people charged off and did concept art, and sound effects, and made assets, and setup scripting hooks, without ever really fleshing out the details of what the system was meant to do. Come to that, I've worked on some non-game projects that did the same thing. :)
