I'm trying to make my ratings based on after sale feelings. If I no longer have a vested interest to "pump" I feel I can be more clear headed.
That said, any game I'm thinking of purchasing I immediately check the list for comments and current ownership status, including new purchase, a few months, a few years, or previously owned.
I've also found pm'ing previous owners a tremendous help. Straight review without worrying about ruffling any feathers.
The number means little to me except possibly for resale.
