Depends what exactly you are looking for. Writing wise the closest would be Pyksies older games "The flesh Cavern" and "Milking It" both being choose your own adventure style stories instead of full fledged rpgs and needing quest 5 to be played.

Gameplay wise Mercanoids had inspirations from "Trials in tainted space" which is the closest that comes to mind if yopu are looking for similar gameplay, together with "Lilith's throne".

And if it's just more general text based rpgs there's "Monster Girl Dreams" and "Divine Dawn".

Can you tell us more about those games? Could be intersting if you are writing for them.
I will say that while I started out trying to write stuff for TiTS wayyy back, this was very early on and I never really played it as it developed much. Gameplay similarities, if present beyond 'Text RPG with combat', are coincidental - though I know TiTS has a shield mechanic, at the very least.
Lilith's Throne, I have played for a grand total of 15 minutes, a very long time ago.
As for what I've been working on;
I did some writing grunt work for

, writing up missions for one of its new star systems to explore. A mixture of SFW and *very* light NSFW allusions, as that specific feature isn't really part of the game's smut focus outside of some of the missions rewarding sexual EXP. This was (for now) a one-time commission, but I might get the opportunity to do more later in the year. I had fun with it!
I've been doing a lot of writing for a game called Dust, a trainer and management type game that's working towards a demo release at the moment. Nothing I can link to at the moment, it's a change of pace and style for me but it's been going very well!
Finally, I myself am working on two projects;
The aforementioned Evilixir is my main project and is going to be a thing I'll be working on for quite some time, I believe. This will be the first game I release a major demo for, but that's a ways off. A mixture of town exploration and dungeon crawling, with both systems linking back to one another as you guide the protagonist, Noxi, towards her goals whilst managing her morale and newfound relationships with spooky, lewd town residents and monsters.
As a release valve from that, and to trial out some concepts I've been messing with, I'm also working on a vore-centric small-scope game called Anarchy Aboard, intended to be a short experience with a few fights, puzzles, optional scenes and a mixture of prey, pred, and non-vore sex scenes. I expect this to be fairly niche but as mentioned I'm trialling concepts with it, such as an RNG-free lightweight rework of my combat system that turns fights into more of a puzzle/strategy experience.
Progress on my own projects is a little slowed at the moment while I work on Dust's demo content, though that's nearing completion. It's very likely that I'll continue working for the game, but once the demo's done I can slow down a bit and focus on my own stuff. Unless other paid opportunities from other devs crop up, of course!
