Rhiannon: Curse of the Four Branches is an adventure game developed by Arberth Studios.  It was originally published in English. However, following the financial collapse of Lighthouse Interactive early in 2009, all European rights reverted to Arberth Studios. The developer then converted itself into a publisher and began selling the English game directly.

In May 2009, Arberth dispensed with the services of Got Game Entertainment following months of declining stock availability in Got Game's North American Territory and a failure of Got Game to pay expected royalties. At August 2010, Arberth is still pursuing Got Game Entertainment for unpaid royalties.

Arberth has since released a German version of the game. A Russian version appeared in 2009, translated and distributed by Logrus. In mid 2009, a group of French and Belgian enthusiasts known as Les Rhemystes completed the French translation and a download-only release followed in the Autumn, again published by Arberth Studios. Italian gaming site enabled the Italian download-only release in 2010.


The game is created by Karen Bruton, her husband Noel Bruton, and her brother Richard Lee, who all cofounded Arberth Studios. They live in West Wales, which they admitted to use heavily as a model for Ty Pryderi. The symbolisms associated with Earth, Water, Fire and Air that are referenced in the game are also taken from a study of putative practical magic that Karen and Noel Bruton undertook a few years ago.


The game is set on the Celtic fringes of Britain; a place where myth and magic spill into reality, threatening the sanity of a teenage girl named Rhiannon Sullivan. An ancient battle for revenge engulfs Ty Pryderi, the remote Welsh farmstead Rhiannon now calls home. She begins to hear unexplained noises, see disturbing visions, and experience other chilling paranormal phenomena.


Rhiannon: Curse of the Four Branches has received mixed or average reviews from general gaming critics, and currently has an aggregate score of 70 on metacritic. Reviewers specialising in adventure tend to be more positive (Gameboomers A-, Just Adventure B, Adventure Classic Gaming 4/5). While the storytelling and puzzles were praised, some criticism was leveled at the graphics and sound, which were said to detract from the experience due to their low quality. The most positive reviews at non-specialist sites came from GameSpot as well as IGN, which stated that "In spite of a few missteps, Rhiannon: Curse of the Four Branches is a good-looking, entertaining and well-made game, especially considering the size of the dev team."
