Puzzle based?

- Anchorhead it's Stephen King/Lovecraft like.

- All Thing Devours it's a time travelling puzzle.

- Spiritwrak it's s Zorkian free as in freedom adventure, were guessing what does the spell do to the world it's part of the puzzle and story.

I was thinking more like open ended simulations.

Perhaps in the vein of 'Footy Fanatic', a football management simulation, https://classicreload.com/footy-fanatic.html

The Kingdom of Loathing [1] is fun. It's not a pure text adventure, it has a GUI and there is hand drawn art.

Spiritwrak has a transcript/walkthrough https://ifarchive.org/if-archive/solutions/Spirit-Transcript...

I avoid these. Also, you could always get the source code, as the game it's free as in freedom.
