Degrees of Lewdity - the gold standard for sandbox, open worldyness and text based games. I've never found anything close to the same level.
My favourite genre, corruption -
Star knightess aura - this is the best one available in my opinion.
Third crisis - thoroughly enjoyed.
I also liked Magical Girl Celesphonia, and Ambrosia. started Enishia and the Binding Brand, also very good but these 3 are quite samey and I feel other from this maker will also be clones of each other.
another genre I would love to see more from but I think must be difficult to make, slave management. From this the best I've found is Free cities + pregmod, the art work side of this game I find frustratingly
