There must have been a couple before that, but Metal Gear Solid 4: Guns of the Patriots blew me away. I had just got into console gaming. I knew little about the game and wasn't hyped at all before I bought the game. Recently Killzone 2 blew my mind the same way. This time I was pretty hyped, but it surpassed all expectations.
I'll add Pokemon Gold, Oblivion, GTA Vice City and Medieval II Total War to the list of landmarks.
