I'm surprised no one said SSB or SSBM. The single player was the easiest thing I've ever done in my life.

After my first playthrough of Shadowgate for the Nes, I was able to beat it again in about 5 minutes. No replay value at all.

Super Monkey Ball : Banana Blitz.

Actually, I remember now: Final Fantasy XII: You beat bosses by putting down your controller and just letting your party decimate them.

Well, if you set it on Very Easy it will be :P

*Checks game collection* I say Luigi's Mansion. Easy and short as hell, but I still like it.

Hmm, probably Dead or Alive 3. punch, punch, kick

DIAL-A-COMBO!

 True, but why in the hell would you ever want to play Shadowgate a second time?

Okami. I kept trying to find ways to make it harder but it's just not possible. You can even use the basic weapon the entire game and win with ease. You guys think Twilight Princess was easy... you should have tried Okami.

Ohhh, HOW DARE YOU!!!!

But actually, that is true. The game was ridiculously easy.

Pokemon Gold/Silver (Silver for me) was probably the easiest game I have ever played. Everything about that game was grossly easy, and the gym leaders were a snore.

Then again, the Pokemon games have been pathetically easy since Gold and Silver, hell even Pokemon Pearl is boring the hell out of me with how easy it is.

There are a whole damn lot of games I've played that were embarrassingly easy, especially recently (Super Paper Mario), but Pokemon Silver I remember just being a pushover.

Come on. These games are not that easy. Try Little Mermaid for Nes or Rushing Beat 3 - aka rival Turf/Peace Makers - for Snes (I never lost in that game - 30 continues).
