I was reading Hacker News comments about the trademarked scent of Play-Doh. I never thought about the smell of Play-Doh much, butit did occur to me that it has a unique scent. But as is often the case, the HN comments that jumped out to me were not directly about the topic. I quote HN user gambiting:

For me nothing beats the smell of Pokemon cards freshly out of a booster pack. I can recall that smell at a whim even though I haven’t opened any packs in years.
I probably have not opened a booster pack of Pokémon cards in more than 20 years (although I have played the Trading Card Game in other formats). But like user gambiting, I can remember the smell and the feeling of freshly opened Pokémon cards.
Introducing Pokémon Red Novel Project by Nicholas A. Ferrell (thenewleafjournal.com)
I introduce a project to turn a new play-through of Pokémon Red into a serialized novel and quasi-strategy guide with helpful tips and strategies.

I am making progress in my Pokémon Red play-through novel project. I am perfect. But what fun would it be to write a serialized Pokémon play-through novel of me being perfect? To make things more interesting, I decided to pretend to not be perfect on occasion. After I pretended to lose to Misty twice, I reached the entrance to Rock Tunnel and realized that I forgot to exchange my bike voucher for a bike in Cerulean City. Of course, there is absolutely no possible way that I could forget to get the bicycle before leaving Cerulean City behind. I only “forgot” to make for a more exciting story and show my future readers how quickly you can obtain Fly after making it through the tunnel.

(Or so I like to tell myself…)
