I was originally going to post this in the toys forum, and just make it about the toys, but I realized that our love for this franchise goes much further beyond just the toys.
So, the Transformers came out in the 80's, and seeing as they are now 30 years old, its pretty say to say that many of us, through some sort of sorcery, have managed to grow up, and start families. Well, maybe not grow up.
Kids change everything about your life. Every. Single. Thing. Thats how it should be. One of the biggest effects it can have is on your hobbies. I know speaking for myself, my buying habits have been greatly curtailed. My displays are mostly put away in storage to keep them safe, and I haven't been able to see the last two movies in theaters.
Okay, that last one doesn't count, I just didn't want to pay for a ticket for them.
Then, the question arises, will your children like Transformers?
This is the stage I'm at with my 2 year old. I'm happy to say, he loves them. He constantly asks to play with my Masterpieces (only figures I still have on display, very much out of reach). I have a few chests filled with transformers I don't care about. Some are broken, most are from the Unicron trilogy. I've given him a couple of those, Armada Sideswipe, Cybertron Hotshot, a broken Animated Ultra Magnus, and a broken Alternators Prowl. He loves them, and will not go anywhere without at least one of them, usually two. I love seeing the joy on his face as he tries to figure out how to transform them, and love playing the hero when he brings them to me to fix.
Then there is the cartoons. He is too young for the movies yet, but I've started him on the cartoons. He likes the original, he likes Beast Wars, but he loves the new RiD show. I've only got two episodes on DVR so far, but he watches them each day. He asks for them (he says cars) and giggles happily as soon as it starts. I've gotten him a couple of figures, Drift, Longarm, and Grimlock, to give him when he is older.
When I was a kid, watching my cartoons (M.A.S.K. and Transformers) filled me with a sense of wonder, excitement, and even magic. Its why I've stuck with them over the many, many years since I was a little boy. I now get to see this joy and magic reflected in my son's face, and that my friends is the greatest feeling I've ever gotten, the greatest reward, from this franchise that we all hold so dear.

Passing it on makes it even better. Thats what I've found anyway, how about the rest of you?
