Overwhored is one of the all-time classics of the Western indie lewd game scene, despite it really starting to show its age. There are newer games that have built on and improved what Overwhored has accomplished but it's still worth playing and stands on its own as a fun RPG.
The story of an ancient all-powerful being being brought back from near death and rebuilding a harem is a high fantasy staple, but this executes that concept perfectly. You get tons of variety between all the different ladies you get to enslave, and each one is brought under your influence by different means, the writing just works.
The art is also highly varied. All the different CGs were drawn by a rotating cast of artists, if mind control is your thing you may recognize a good chunk of the artists involved and they all brought their A game.
The game has a healthy mix between gameplay and story elements, and manages a good difficulty curve all through out. The gameplay might get a little tedious after a while though, especially if you don't like navigating through dungeons swarmed with enemies.
Overall, great story and great characters. Some elements don't hold up as well as they did in the early 2010s, but still highly worth recommending.
