Call of Duty, Assassin's Creed Revelations and Skyrim.

Bioshock bored me after great reviews. In general, a lot of modern 3D games I find to be somewhat over rated because they rely on style over substance. I do enjoy them though.

Oh, forgot Metal Gear Solid. I tried the psx-version several times and couldn't get into it. Tried the PS2-version, which also didn't catch me. Never tried the PS3-version...

Uncharted, God of War, Gears of War

i never heard anyone say good things about Revelations, it got the worst reviews in AC games. it was avarage reviews as i remember, why would you call it overrated?

Mario and COD? No way. Those games are pure fun. Original? Not anymore, obviously but that formula isn't broken.

Assassins Creed (the whole series)

Anything Call of Duty, Grand Theft Auto 3 and 4.

Uncharted. Its just Tomb Raider, with a dude. Nothing special.

Call of Duty. Need I say more?

Assassin's Creed. Quality is a bit overhyped.

But, the worst offender of being most overrated is ff7. Its a good game, but isn't NEARLY the best game of all time.
