I'll second Koffey and Hobb for players of the year.
Could I suggest another category? Best Sounding Board
It'd be for those that give help to others when building characters or cities. Sorta similar to Best Board Contributor, but on a more personal level. I'd nominate HobbitGuy1420 and KOFFEYKID for this. In chat, they are some of the people I talk to most when trying to suss out a character idea, or stunt/power, or plotline.
