With Monopoly, I have been doing this thing. I bought a bunch of versions, tossed the boxes, and stacked the boards into one box case.
I have been collecting game pieces, hotel sets, you name it.
Now, I have those crafting cases and fishing tackle boxes with those cubby holes. I have all these different hotel sets, game pieces from limited editions I hunted for. I have the cash credit card thing. (For those jerks for like to keep hiding their 500 bills so we forget about them when the hit Boardwalk, jerks)
So it's all sorted and it's like the Ultimate Monopoly. (Cost me enough)
