These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Do Not Do This Cool Thing: Possibly feared by the ESRB, as the development of Bejeweled 3 suggests. The ultra-relaxing Zen Mode was not only intended to relieve stress, but also to suggest different things to help smokers quit their addiction. Unfortunately, that part didn't make it to the final product because any game that so much as mentions smoking,whether positively or negatively, would end up with a restrictive rating mentioning "tobacco use" and rather than the otherwise-appropriate "E" rating.
