I remember opening the Sears catalog and seeing what must be the sequel to Super Mario World. I shovelled driveways and busted open my piggy bank - it was a full price Nintendo game and I had to have it.
I started my subscription to Nintendo Power after that...
I was in a video rental store, saw "Mario is Missing", and like you assumed it was a sequel to "Super Mario World".
Got home to play it and was just flabbergasted. I don't think I played for more than an hour before complaining to my parents. Luckily they're nice people and they had more errands to run that day. So back out we go, back to the video store we end up, time for me to pick a new game to rent.
Oh, "Mario's Time Machine", now that's a Mario sequel guaranteed to be fun.
Mario and I were not on good terms for a long while after that.
(For those not in the know, "Mario is Missing" in an educational Mario game about geography, think Carmen Sandeigo but not fun. "Mario's Time Machine" is basically the same game, but time.)
