Yes.
MGS was awesome, loved the story line and loved the little things you had to do, like look at the back of the CD cover to get the codec code for Merril, really clever. The begining was sort of tough, low health and no weapons. But overall that game was in your face stealth. MGS1 >>>>>>>>> any other stealth game.
MGS2 was good but I was a tad disappointed in not having Snake as the main character.
I have MGS3, but haven't had time to play it. It looks good from the parts I have played, especially dressing up as an alligator.
