What is the biggest known game collection?

[vintagegamecrazy]

I am just curious, but what is the biggest game collection as far as numbers? I've heard of several members that have 7,000 plus game collections, I have a friend nearby me that once had over 10,000 games and over 70 unique systems. I just want to know what is the biggest known? 10,000, 12,000, 15,000 maybe more and how many systems? Just really want to know.

Thanks
