Hmm... That does bring up a question for the judges, if I may: are there any gameplay genres that should be avoided due to one or more judges disliking or dismissing them? For example, would a "walking simulator" or a visual novel be marked down (perhaps in the "gameplay/fun" category) just for being such?
Honestly this is a difficult question, what one judge likes, another may dislike. even though gameplay/fun is a heavy category, i've always felt most judges were able to set aside any bias they have toward a gameplay type to make a fairly objective call. This is why you should also seek outside play testers(family, and friends are a good resource if you can have them spare a few minutes) to ensure your on the right path, and not blinding yourself to making something that might not be all that fun, or needs work to polish off some of the unfun mechanics.
