His collection doesn't seem very big to me... :/
Please tell me you are joking right?
Here's my take on it: I think the collection is absolutely amazing and very impressive for one person to have amassed. Also, I think some of you are undervaluing just how much that whole collection might have cost the guy. I'm gonna guess he's got a solid 50 to 75k into it. And the time....ohhh the time. Even if he just sat and pressed "Buy-it-now" on ebay again and again, there's a considerable amount of effort that would have to be consumed to get to this stage. I don't envy the guy, but I certainly respect what he's put together there.
I get the feeling this guy got everything on the cheap. I also think the displays make the collection look bigger than it is. Although it is still a big collection
There is a point where he mentions that he is trying to get all the Myst games. If he was spending money, he could get all of the myst games. He has a LOT of the games that you can easily get in trades and from flea markets.
A lot of the boxes (the konami laser scope for example) have gashes and such that make it look like flea market finds or things purchased on the cheap.
I bet he has spent a lot. But I saw nothing that would be mega expensive except a few pieces of hardware. No new systems. It is quite possible that his budget is less than a modern gamer buying new releases. Watching his pickups videos, he definitely digs around for cheap buys in the wild, does trades, etc.
