I have to throw in with the idea that the questioner very often doesn't know what question he's trying to get answered (the "is it good" meaning possibly "would i like it" meaning possibly "do others like it" meaning possibly "is it worth a few bucks for" meaning possibly "will this contend with other games as my favorite", etc., etc., etc.).
Defining the question, and redefining the question, and breaking down parts of the question into basic edible chunks... that's not a bad thing. A specific question, agreeing with Shog, may be a very general one or a different one altogether; a general question may actually be specific. Exploration isn't bad... I think we'd be all a lot better communicators were we to accept that at the outset...
That questions of "is it good" will have to relate to something else--as there isn't any "goodness" itself inherant.
