@virion This is basically the principle that "only the happiest or the most unhappy people leave feedback," right? Therefore, no forum (or steam reviews or whatever) will actually be representative of the true population of players?
I could accept this, with the following caveat. As this product is in EA, many so-called 6-8s might have a stronger desire to participate in the forums than they would otherwise. Quite possibly to advocate against changes by saying that they're happy enough with the current game. This would actually increase the number of "effective 9/10" posters.
Or the opposite could happen: people who would otherwise just rate the game as "fine" are encouraged to find flaws that they'd otherwise not comment on...
