Eh I dunno dude, he has made plenty of CCGs after Magic. He has even helped on F2P digital CCG in the last 5 years or so (SolForge).
Richard Garfield is a lot of things and he is very very clearly passionate about games and the purity of games, but he also knows how to make a thing for a business. Even the Living Cardgame elements to Android: Netrunner is still about baking in a repeat customer model.
That said also agree quoting prices for a Vintage deck or a high power EDH deck is really disproportional on """"Value""".
That also said though, holy fuck the people in that comment chain that down play just how fucking expensive competitive magic is are fucking bonkers. If you think that most people A) can or do offload their collection onto the secondary market you are delusional and B) if you realistically think the value of your collection is close to recouping your costs you literally aren't buying a single booster ever running purely on buying singles for your deck and are praying there isn't reprints of your best shit.
Checking
here at a site I don't know and am relying on Alex to tell me if I am dumb, but it lists the price of current tournament decks. In Standard this month the majority of decks are $200+. There is a handful of cheaper decks through out (Mostly a mono red burn deck popping up), but most of them are significant investments even for something that will stick around for 3 or so months in a stable meta. Online scrapes it together a bit cheaper.
Pauper decks run $50, but literally anything competing at the top levels (which trickle down HARD in M:tG) in other formats is hundreds to thousands of dollars.
You could run proxies but then like, well yeah you aren't competing in sanctioned tournaments and the game could literally be free other than the cost of pen, paper, slips and a few decks of playing cards (or just playing on Chimera).
EDH is a bit less competitive meta to it, but even just a fuck about EDH deck has to be 100 cards with a Legendary in it which unless you are Kamigawa based that's going to be a $value right up front to play just on raw rarity.
You can also only partake in Limited tournaments, but well I hope you are winning constantly and then reselling your cards or you are spending every single time you play.
Magic doesn't have to be a tens of thousands of dollars up front to start investment, but anyone claiming in that comments section Magic isn't really fucking expensive and puts it on even the same scale as Hearthstone is delusional. Standard in HS is going to PUSH it in that direction, but HS always has that baked in initial cost that keeps giving in the Classic set. MTG has constant treadmills and reprints Core and shifts around what is in it every damned year. It is a whole other beast.
It is also not Richard Garfield's to answer for in it's current state. edit more response to Jim. Even out the gate MtG was a different beast than he expected it to be. The original idea was for it to be the base set was its own thing. Then you could build new versions of the same game. Expansions and mixing them together was an after the fact thing. He was still involved and a huge factor for many years afterwards, but it is less him driving the decision making. By now the tournament scene, the formats, all of that don't remotely resemble when he was involved and even for those a lot of those are other people's babies.
That said I 100% agree, Richard Garfield made games for businesses that he knew would sell. He does a mix and match of "pure" games that are just games he wants to do purely to do them and games that are compromised for the sake of business. It is still working on something he wants to do, but he is plenty realistic enough to be able to be part of a corporate entity.
Edit - responses from when I started typing this is for Dunie.
RG is a lot of things and is super smart. He is a bit vague on defining the addictive behaviours I believe because of all the things he is, a psychologist is not one of them and he knows it. He is a master at games design and a mathematician, writing an article as a gamer. He can speak volumes to player behaviour and responses, but he isn't going to sit there and disect the mountain of various layers of operant conditioning that makes up most games that we tend to dismissively refer to as "skinner boxes". Probably not the place, not the audience and maybe not something he is comfortable even doing (though he can most definitely point out the degree of randomness in the reward/punishment outcomes from the various levers in place).
