Ja, I tend to "enjoy" the games I buy, and by that I mean I don't rush or skip stuff. I'm pretty obsessive-compulsive, as well, so every treasure chest must be found, and most sidequests should be satisfied before I even attempt the final dungeon. I've never found such stats on other sites helpful at all for this reason.
Plus, most of RPGFan's reviews allude to the length of the game in the text itself. Good ideas, though, keep 'em comin'!
