You sir have a sad, sad misunderstanding of what a lead designer does on a game and what a director does for a movie.
You sir are mistaken. Creating a videogame is much, much more work than creating a film. Reality provides filmmakers with physics, objects, actors, textures, particles, lighting, sound, animations, etc. Game developers have to develop all of these from scratch. A lead designer's primarily role is to outline a game's overall vision. However, this very broad vision is greatly influenced by everyone else on the team. Animation scripters deal with the intricacies of balance and mechanics in general. Level designers are assigned specific levels and are the largest factor in their outcome. A lead designer supervises all these things but his overall impact isn't nearly as significant as it is with a director. And again, game developers have to do significantly more work than filmmakers. Since the work is much more even, the importance of any single position is greatly lessened.
I'm sorry but Boon doesn't deserve a $1 million bonus when you compare the work he does to the work everyone else does.
