Stygian Reign of Chaos was pretty good, just a shame the devs ran out of time and money so it was left blatantly unfinished
but until the (abrupt) end it's sorta like a horror Arcanum or Planescape with some VTMB Malkavian stuff mixed in for good measure

as an actual answer to your question, it's because
>a) every attempt to make a lovecraft game is made by fans who are passionate about his work so they set out to make something really fucking good but they don't have enough time and money to do everything they want so the end result ends up being an unfinished mess, see for example Call of Cthulhu Dark Corners of the Earth, Call of Cthulhu the Official Video Game, The Sinking City, ect ect
>b) basically no one is making CRPGs nowadays outside of studios like Owlcat and Larian who are too busy with other projects, and Indies who don't have the money to make anything significant
