I can definitely appreciate that nostalgia factor. I was fortunate enough to experience G2 of Transformers, which gave me some less cool paint-jobs for my favorite characters but gave me them nonetheless.
I'll always remember when my brother got me the re-issue of Optimus with the black trailer, or when my dad bought me Ninja force Snake Eyes(my first SE though commando was always my fave). I'm a big robot/ninja fan though, so the muscle men MOTU didn't appeal quite as much.
So I gotta ask, what's the pull behind MOTU?? Besides nostalgia of course. I was born a year or so after the crash of the series, and I've always wondered was the craze was with the half-nude muscle men, especially with the hype of Mattel's shop. I've thought that more than a few were awesome looking, but never got into it. I figured you would know, so I thought I would ask!
