What's interesting is that I used to be the same way, and lately I've turned 180 degrees on that... I make my 8 yr old see every platform version of games that interest him, mostly as a history lesson. He found my N64 mariokart, and I went back in time, showing him the arcade version of donkey kong, and how it evolved into dkjr, dkIII, super mario bros, then mario world, super mario world, yoshi, dkcountry, mariokart, etc etc etc exposing him to the entire nauseating mario franchise.
To my astonishment, he was so interested in all of this, he decided to do an essay about it. Before we were done, he had branched out to all ports dk (coleco, apple, atari, c64, etc)... and now his favorite thing to do is find all the ports of a certain game, asteroids or whatever, and compare/contrast the way it was done for each console.
Anyway... sorry didn't mean to get off topic. I do like your quest. I'll see if my boy has any thoughts on ports that ADDED... I think his general assumption is that they always suck somehow.
