I had always thought that D&D was the coolest thing you could have in a house. I would definitely love to have a collection of that, and be able to play it, because I haven't had the chance to do it. Hero Clicks? I don't know them, I'll google them.
I'm not so much in agreement with the fun of looking for it, it seems to me that you feel more satisfaction when you have them, and a feeling of challenge when you think about the next one, than the hunt itself.
