It's crazy how much money people end up spending on these kinds of things. A hundred here, a hundred there, before you know it you've spent tens of thousands, maybe even hundreds of thousands. Most probably don't even realize they're spending that much.
I never completed it, but since then I have played the smaller (Monopoly board size) game, Warcry.
The friends I discovered were playing the full-size games spend hundreds every week or two.
