If you want to read more of this author then I can recommend you the lawless ones (It's free to play here with this link): https://forum.choiceofgames.com/t/the-lawless-ones-previously-villains-completed-remake-in-the-works/30192
I always found price of freedom always a bit unique and a general oddball of the site since stat-based games are not a norm here. (I have mostly read the fantasy corner, so most of my recommendations will come from that genre. The one marked in red have more sensitive material than POF in case you're underage.)
If you really like the sad and gritty feel
I found that rogues and necromancer fit the bill. I do lean against rogues as the tone is about the same as price of freedom
If you really like the combat aspect then there are also plenty of hidden gems:
Arakhan’s Vengeance: For a person who doesn't particularly like combat scenes, the scenes were sleek as hell. I had replayed it multiple times.
Delve!: It plays like a genuine RPG. (Also check out the author if you like more gamey storygames.)
If you like the chapter based/story arc like structure
The best example that I have read is "the book of vanishing tales" where most of the arcs can be enjoyed as separate entities, but are interlinked in a larger narrative.
You also have "the tale of the foolish princess" which does it a bit more loosely.
If you like stat managing in particular
You have them in two flavors
the Magellan series: The ending is more or less set in stone, but you have to carefully manage them in order not to die.
The knights of the golden sun: these stats don't have an effect on the flow of the story, but do have an effect on the ending
