Quoted from kool1:
You and I may know what you like and don't like but for some one who knows nothing, it's some kind of a guide!
It can't be a guide if the person doesn't know what they like. They need to play games to figure out what they like. If I were green and didn't know what I like, I'd be guided to the top 10 as being games I'd love. But in reality out of the top 10 games (as of right now) I flat out don't like 4 of them (Godzilla, JP, Iron Maiden and TZ). I am so-so on MB. (Even though I had a gorgeous one for years).
Love MM and AFM, but my all time favorite game is 30th (ToM). That is not a guiding much at all. So according to the list, I don't like #1 (Godzilla) but love #2 (MM) That isn't guiding, it is confusing. Going by the list, games I flat out dislike are "much better" than my all time favorite.
So I'll have to disagree with you on the 100 rankings being useful. I think that they are worthless and just a gimmick. Every person has their own likes/dislikes and folks need to play them to figure out if they'll like the game.
Like I mentioned earlier, designers are a much better gauge of whether I'll like a game.
Except Gomez. It can go either way with his. I love Johnny Mnemonic and Bond whereas I don't care for LoTR, Avengers or Sopranos. I like fast, flowing games. Stop and go (or slow) games bore me.
