Toys, games, knick-knacks, opportunities?
Another idea I just had would be for them to auction off the right (priviledge?) to choose the next figure they make.
Imagine, being able to bid all the points you have earned (purchased, really) over the years and exchange them essentially for the one never before made and not likely to be anytime soon, action figure of your choosing. Now this would really be a "reward" and a "thank you" from Hasbro to us for spending so much money on them over the years. And truly, the person who has the most points (and is willing to spend them) is probably the one worthy of this method of thanks from Hasbro.
Sure, a bunch of people would be like, "What a moron, I can't believe he wasted his auction winnings on getting that figure made for us!" But, more likely, the winner would pick something that most people have been clamoring for for a long time, like the Tonnika sisters or something.
What do you guys think of that? Would Hasbro go for it? What are your ideas?
