The topics seem solid. Instead of best soundtrack wouldn't best use of music be a better category. That will include stuff like the new metal gear solid game where I'm not sure the soundtrack is amazing but the way they use the music is kinda great. Your Walkman/ tape players around the camps (of which you can take the Tapes to use later.
Yeah get rid of non-traditional controls and just go with new mechanic like west suggested.
While I'm a bit of a minimalist and would rather streamline the categories more, if you want to expand you could possibly expand it out by including more worst categories or include the industry as a whole. Best fraudulent advertising, Best DLC milking, Best food/beverage tie-in, Most egregious insult to customer intelligence, you know? Stuff like that. Of course this year Fallout 4 will win most of these, but Destiny may take the sloppy seconds.
Konami would win by a landslide if you did it this year. Even the Destiny fuckery is but a poo pellet swirling in the vortex of the shitstorm unleashed by Konami.
Most of the games I've bought this year are of a niche genre/category. Highly doubt the games I've played are ones that the current noobtoobers are ones they've even heard of.
I've been a bit out of touch with all the Triple A games titles. This year has been all indie titles and rhythm games for me.
