I think everyone on this site should try at least one of these stories, whether you're a writer looking for inspiration or just someone who enjoys playing text based games in general (if you didn't you probably wouldn't be here). While these games are not entirely text based like the ones on this site, and still have some exploration/combat elements that are graphical, all of them (Except Year Walk, but that's a unique case) have the vast majority of their exploration shown entirely through text descrpitions, which is the critera I have chosen to count them as "text-based video games).
I'll give a short overview for all of them so that you can see if you think you'd be interested:
1. Sunless Sea & Sunless Skies
Both of these games are part of the same series. Set in the "Fallen:London" universe, a world where London has been dragged underground by eldrich bats and sunlight drives people insane with bliss (it makes even less sense in context), this is a particularly strange world that's almost impossible to get your head around, because the deeper you get into the lore, the harder it is to understand. It's possible to get a general idea of what's going on if you dig deep enough though. The "island exploration" is text and choice based, but the "ship" exploration and combat is more RPG/Roguelike in nature.
The gameplay involves taking your ship to different islands in these eldrich locations, where each island has some eerie goings on, from haunting to cannibal cults. There's also a "sanity" meter, where if your ship spends too long in the dark (or you make risky choices when you get to the islands), your crew goes insane. There's a good deal of supply management, with you having to get enough food and fuel on your voyage. This is probably the most famous of the games here but it's worth including because it is very well written and thought out.
2. Year Walk, Device 6 and The Sailor's Dream
(You might be tempted to look for guides to these games online when you get them. Don't do that if you can help it, it will ruin the experience)
These are three Simogo games for mobile, and unlike 99% of mobile games, they are all incredibly cleverly done. They actually take advantage of the medium (some of the puzzles, for example, involve you having to change the position of your phone in real life, and turn it on its side to read text). Year Walk is an eerie game heavily based in European Mythology, where you have to explore beautifully drawn woods on a cold winter's night to learn the future, encountering faithful representations of the ghosts and creatures from these mythologies. The "text based" part of this comes from the Companion App, where the second half of the story is told entirely through text, but you need to apply the things you learned on your first adventure in order to complete it. Device 6 is an eerie mystery set on a strange, abandoned island, told mostly through text, but with a few visual puzzles sprinkled in.
The Sailor's Dream is one of my favourite games of all time. It's easily the most immersive experience I've ever played (I've tried VR games and they don't even come close to how immersive Sailor's Dream is). You have to explore a series of islands (a running theme in these sorts of things I've noticed), uncovering the mystery as to what happened to a young woman who once lived "in a house, on a cliff, by the sea". This game will take you at least a week to uncover, and you'll have to really imagine you're there in order to solve some of the puzzles it poses (if you do buy this game, make sure you start it on a real-life "Monday". Trust me, you'll enjoy it way more if you do this.)
3. The Witcher Tales: Thronebreaker
Part of the famous "Witcher" series, this is set before the RPG Trilogy, where Queen Meve has to free her land from the overwhelming might of the Nilfguardian Army. While you go from one location to the other in a top-down, isometric format, the actual descriptions of the towns, forests and swamps you explore are all explained via-text, which allows for a much greater degree of choice and consequence than the more "mainstream" RPGs. In terms of choice and consequence, this may be the best mainstream video game I've ever played, because seemingly tiny, insignificant moral decisions often have HUGE impacts that you sometimes won't even realise until you choose differently in a second playthrough. The game does a great job of not shoving any kind of agendas or moral positions down your throat (a quality that is not to be overlooked...), but simply shows natural, logic consequences of each action. If you play this game, I would certainly advise you to "go with your gut" and choose whichever option seems best to you. The combat in this game is card-based, which I personally find very fun and rewarding, but it's also a relatively unusual choice for some people, though it's quite easy to get the hang of after a while. (Also, one of the locations in the game is, quite easily, the most disturbing place I've ever been in any video game I've played. All I have to say regarding that is Gvaern Ichaer...)
I really hope that at least one of these games is enjoyable to play. (If you're squeamish about horror elements, then the only one I could really recommend in good conscience would be "The Sailor's Dream", but even that is really both eerie and sad.)
