@Vhailor: You do have a point, even though I have a hard time believing that someone that plays games for fun or is a fan of something can truly be 100% objective. I am not saying that one cant see the faults of a system (like you pointed out with the exp ratio) and imo its probably easier with something like a movie but a game?
For example if you hate plattformers and yet you have to review one. Can one be truly objective in it? Isnt there always a part that will influence this? In the end I believe that fun alone is not good but still something that SE can use for future content.
If someone posted that they found Eureka fun, then for us this is not really a deep look at it but SE can say that this person liked the way it was done. So if more people are of this opinion they know that their content works because people find everything as fun. If someone writes that they dont like the content itself but found it at least fun with friends, then SE can take from it that some people will do content that they dont like if they can do it with their friends. If someone writes that they did not find it fun because of x then SE might know that x might not be the way to go and can conclude what the people might like instead. All of this was founded on the feeling of fun with the input of why its fun or why its not.
About Eureka and its content: Well in a recent interview they said that they have forseen that people might react that way (Fate trains) and even just wait in town for a spawn, so can it be really objective broken if they have forseen it and are fine with that? I do agree though that bugs exists and those might count into buggy content.
But yeah maybe we are talking about the same thing in a different way. In the end its important to ask if they take our feedback into mind and listen because we players are the most important part in this (without us they could not produce the game further) and for me it feels like they dont often listen that good. I mean otherwise I just question why we have something like Diadem 2.0 if they did..
