Expert's point of view on requirements prioritization in video-game preproduction

This short survey (just 7 questions) explores the industry experts’ point of view (i.e. your point of view) on Requirements Prioritization (if you are not sure what RP is, don't worry, there is description and a few examples later). The first several questions touch requirements prioritization in general. In the last couple of questions, the emphasis is on the factors that make entertainment software different from, for example, spreadsheet software. Keep in mind there are just a few questions, so please elaborate on your answers and present your point clearly!
