I find written review from a few trusted Pinsiders to be more valuable than a position on the list (Caucasian2step's review come to mind.) I value complex, balanced rules more than most other factors. By contrast, many others go for what has curb appeal.
The top 100 is an OK rough guide, but I could like a game at #35 more than the game at #1 (and in fact, have at points.) Often the games below 150 are going to be flawed, but are mostly still pretty fun.
