Thank you for making this site. I think its important that people think more deliberately about the kinds of game mechanics they find fulfilling. I would point out that what may be a dark pattern for one player could be a desirable feature for another. For example customization can be used to exploit the sunk cost fallacy to the detriment of casual players, but others might consider that investment to be a good part of the gameplay as with some rpgs. It might be useful if people could express the magnitude of effect a pattern has on the game with some kind of numerical score. That would open up the possibility of eye catching data visualizations.
