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.
