Yeah, I get that, I am just saying that I look at your site, I see all these numbers next to a game, and then there is some overall some of the numbers, but there is no rating for the really the only thing that matters - a "fun factor"
Take for example one of my favorite MAME games - Pigskin football 621 A.D. Graphics are average, gameplay is overly simplistic, sound is nothing to take notice of, etc. From a ratings standpoint its pretty mediocre, but its pretty fun to play. Its cool you have these different buckets, it just takes away from the most important point, and really the main goal of what you are trying to accomplish - trying to tell people which games are fun to play.
