>Paczynski says they once hired a private investigator to find someone living off the grid in the UK. He had unknowingly inherited the rights to several games

My grandfather was a "landman" for oil companies tracking down mineral rights and has all sorts of stories like this. It can all get messy and weird fast.

Stuff like tracking down people you'd assume would be dead but are in fact ancient and alive at 103 in a nursing home. Convincing a bank that through a series of mergers and acquisitions that they are the rightful owners of the mineral rights to a piece of land foreclosed on in the great depression by a bank that itself failed. Generations of poor people dying without wills or settling probate. Inheritance battles spanning generations until no one alive was around for the start. Step mother that swooped in and married a man at the end of his life, inherited everything, remarried, had kids and left everything to them instead of the step kids.
