Your subject it not controversial at all, its just a comparison between Games and VFX. Now there is little difference with the way the work flows go for either of the 2 sectors (and VFX is learning a thing or 2 from gaming ATM) i think it would be pointless to do this subject (sorry).

Why not talk about the way parents blame the games and movie industries for the wrong actions of their children, it comes down to the violence factor again, but if its written with both viewpoints given objectively it could make for a good paper. You would make 6 pages easy on this topic and it is one that will not die (for the foreseeable future).
