i think the near-extinction of people making fun, deep and/or unique interactive text-based browser games, projects and stories is catastrophic to the internet. i'm talking pre-itch.io era, nothing against it.
there are a lot of fun ones listed here and here but for the most part, they were made years ago and are now a dying breed. i get why. there's no money in it. factoring in the cost of web hosting and servers, it probably costs money. it's just sad that it's a dying art form.
anyway, here's some of my favorite browser-based interactive projects and games, if you're into that kind of thing. 90% of them are on the lists that i linked above.
A Better World - create an alternate history timeline
Alter Ego - abandonware birth-to-death life simulator game
Seedship - text-based game about colonizing a new planet
Sandboxels or ThisIsSand - free-falling sand physics games
Little Alchemy 2 - combine various elements to make new ones
Infinite Craft - kind of the same as Little Alchemy
Tamajoji - browser-based tamagotchi
IFDB - interactive fiction database (text adventure games)
Written Realms - more text adventure games with a user interface
The Cafe & Diner - mystery game
The New Campaign Trail - US presidential campaign game
Money Simulator - simulate financial decisions
Genesis - text-based adventure/fantasy game
Level 13 - text-based science fiction adventure game
Miniconomy - player driven economy game
Checkbox Olympics - games involving clicking checkboxes
BrantSteele.net - game show and Hunger Games simulators
Murder Games - fight to the death simulator by Orteil
Cookie Clicker - different but felt weird not including it. by Orteil.
if you're ever thinking about making a niche project that only a select number of individuals will be nerdy enough to enjoy, keep in mind i've been playing some of these games off and on for 20~ years (Alter Ego, for example). quite literally a lifetime of replayability.
