I remember as a kid when I first had a NES, before Super Mario Bros was the pack-in game (mine had Gyromite and Duck Hunt).  For a birthday or something I asked for Super Mario Bros, and ended up with Mario Bros.  It was kind of disappointing, but I didn't let on, and learned to like that game.  Now, not so much.  I think I overdosed on it early on, and now find it to be pretty boring.  
So, in a roundabout way, I sort of agree with shorthair, which terrifies me.
