Are Achievements Your Personal Video Game Ratings System?

In today's Speak-Up on Kotaku, KillerIri5h notices a strong correlation between how much a player enjoys a game and the amount of achievements unlocked. Can you use achievements and trophies to rate your games?

During a lazy moment today I decided to look through my past achievements on my X360. As I scrolled through 100+ games that I've played over the last 4 years I noticed a trend. Any game that had 500 (or more) of the possible 1000 points unlocked showed that I liked the game. Any game with less than 500 points meant I didn't really enjoy it (and anything with less than 100 meant I hated it). While there were a few exceptions to the rule, for the most part, it held as I scrolled through my game list.

For me, achievements and trophies have become part of the gaming experience. When I say this though I don't mean a part of the "achievement whoring" experience. I'm not going to try to get achievements/trophies on games I don't like. But if I like a game I will take the time to look at what achievements/trophies are there to be unlocked. Almost like side quests or personal challenges the developers are issuing to the players.

So does anyone else notice this trend on your gaming system of choice? If so, what is the number that lets you know if you liked the game or not?
