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.
It's Hard, so It Sucks: Beginning with pop'n music 20 fantasia, the COOL judgement is forced in Normal mode. This has led to even higher-end players complaining, as having COOL enabled means that a performance that otherwise nets a near-perfect score with COOL off can become a measly 50,000-60,000 pointsnote The max score is 100,000 play when COOL is enabled.
It's Easy, so It Sucks: Then when the scoring system was made easier for Lapistorianote previously, the Cool-Great-Good-Bad scoring ratio was 10:5:1:0; as of Lapistoria it is now 10:7:4:0, players were very, very unhappy. This isn't even a Broken Base anymore because MOST players are complaining about it.
