The games on this list aren't neccessarily bad games or over-rated games. They are just games that were over-hyped to the point of ridiculousness and didn't end up delivering what was promised.
Here are vgchartz.com's Top 20 Most Overhyped Games Ever.

When thinking of the “top ten most overhyped games ever” list, I realized that one list alone was simply not going to cut the mustard. Basically there is a problem with lumping modern games in with older ones, due to the advent of the internet. Some almost mundane games seem to get a shedload of over-hype, which the most successful game “back in the day” would even hope to get. The internet has, in a way, made us far more susceptible to developer, fan, publisher, or media hype.

Remember, just because a game is on this list does not mean it is a bad game or “over-rated” but that it was over-hyped to an unrealistic volume long before release. In many ways, this sheer overexposure to a game can ruin the game due to bad reviews, or unfair expectations, and in other cases, as you will see, some games were overhyped for no real reason alone.
