Entire article comes down to this quote from an interview:

“When Magic was first designed everyone had their own treasured collection, but those treasures became commodities, and we lost some of that magic. Since then I’ve been trying to figure out how to get back to that.”

Edit: Also potentially worth noting, he was doing press for a new video game when he said this quote.

It went to shit when Hasbro decided we need a new set every 5 minutes.

Probably when wizards of the coast was bought by hasbro.

I enjoyed the read, thanks for posting. The two big themes of the article seem to be:

• money ruins gaming

• the customer is always wrong

It went wrong when the cards became an investment.
