There are two games released in the Barrow Hill series. The first one (Curse of the Ancient Circle) was released in 2004 or 2005 and Barrow Hill: The Dark Path was released a few months ago. Supposedly there is another game in the series called Bracken Tor in the works (

Both games released so far are very much worth playing and I consider the first one a minor adventure game classic. I recently replayed my old DVD copy and it worked perfectly on Windows 10. Both games available on Steam.
