If you were to invest money in creating a videogame -let's say a story driven adventure- and you had to hire the whole team (artists, coders, musicians, writers, ...) what do you think would be roughly cost? What kind of team do you think should be hired? What would you outsource? What would be the time to market you would aim for? And what platform(s) would you launch on?
