game to easy?

Ok, i did play the game at second easiest (regular) mode, since I'm not some every day player, i just play gmaes ocasionally (and i usually suck at them lol), but I found Call of Duty 2 so easy, that it was even boring to play, I could just ran and kill everyone with little trouble.
I also played COD 1 at the same difficulty and it was quite harder, and I played COD modern warfare 2, also at regular and it was challenging, really intense playing, much harded then cod2.
