I think there are quite a few other games that could be added to the overhyped on video game forums list. I have to say God of War is the overhyped game that bugs me the most. Reading reviews of it and listening to Sony fanboys it's God's gift to gamers, one of the greatest series of all time, etc etc etc, and yet GoW1&2&3&PSP combined will likely fall in the range of Halo alone in sales. Sales-wise (I don't care about how great the game is or isn't since that's different for everyone) I think Lair, Heavenly Sword, Assassin's Creed, Mass Effect, Bioshock and the rest will fail to light up the charts. They'll do alright, but they'll be more Lost Planet/Crackdown (if that) and less Gears of War/Halo.
I totally agree. I remember them bragging about how GoW2 had a million pre-orders. Then they mocked Pokemon for only have 500k pre-order and the people standing around waiting for Pokemon was just an ordinary crowd in NYC.
