The internet nerd version of those Pay-It-Forward chains that happen in the Starbucks drive-thru every now and then. Some people might be sold on the idea alone but to me it was basically just a proof of concept and nothing more.
I remember having this in my Steam wishlist/library for years but never got around to playing it until now which is a shame because the offline version doesn't have the same impact. I am a sucker for a concept like this though!
