Sounds like a great idea! I often wish that I had the chance to play the Putt Putt games when I was young; and I am sure there are lots of people who DID play with Humongous games and that experience I am sure shaped their love for gaming.
Thanks, I actually wrote up a script of about 3 pages or so of what I want to talk about - popularity and sales potential, the games acting as a "gateway" to other p'n'c adventures, art direction, "clickits" and minigames increasing gameplay length, music styles, work put into characters, and the stories, especially Pajama Sam. That's about the gist ofit.
I'll probably have clips from a variety of HE games to emphasize my points, as I think I have a process I can use that will work.
This sound like a really neat idea.
One more thing you may want to showcase is how many of their games featured alternate pathways on different playthroughs, which also substantially increases gameplay time.
In Pajama Sam 1, for example, the Mask, Flashlight, and Lunchbox each have two locations where they could be with one being randomly(I think) being selected for any given playthrough.
Also, as I've gotten older, I really appreciate the little Easter Eggs in the games, like In Pajama Sam 2, if you have Sam put on the Hard Hat in the WWW lobby and wait, he does the "YMCA" dance as his idle animation, and in Freddi Fish 1's intro, she meets a fish that not only looks suspiciously like Putt-Putt, but is named Jason and voiced by Jason Ellefson, Putt-Putt's (then) voice actor.
