I prefer to think positively and I think that if everyone did that things would be a lot better for everyone.
As a judge and an entrant, I liked the mandatory feedback rule and was disappointed that it was lifted this year. It proves that people have played a game enough to comment, which is my personal threshold of whether a game has been given enough time. Never mind that e.g. some judges just don't like some types of games, or are not good judges, or whatever - at least this rule ensures people have played a game enough to form an opinion that can go into 100 words. If you can't play 16 games over a month or two enough to write 100 words on each, consider not being a judge.
Entrants should have to enter their games into the individual categories. In this respect we would have some initial self-selection by entrants themselves - if I'd made a game that had mind-blowing level design or game mechanics, but graphics that looked like Asteroids, I'd not be expecting a nomination in 'Visual Art' but would consider entering in the 'Design' category. This would enable judges to approach a game in the right frame of mind, and not dismiss games that look, sound, or play a certain way just because of that one failing. It also would make people think harder about whether their game is competitive in each of the categories and ultimately if it is actually worth entering the game at all (many games entered in the IGF are not worth entering in my opinion).
Now this is something I think IGF should strongly consider, it would help with a lot of problems in my opinion.
It would help alleviate judging games under every category pointlessly and let games be judged, sooner by more applicable judges to that category, on what they think themselves possibly worthy of merit (eg: a Nouvo award and not its graphical fidelity).
Perhaps it costs half the current price to enter one category, but obviously that stacks by entering more. Even under the same pricing structure I think it would help though.
The grand prize could still be nominated from all the games entered to the other categories, and a game could possibly be nominated into another category as well if enough judges think it apt?
