The initial impression of Rhiannon for me was of a game in the vein of 7th Guest or Myst, in that I felt there was something just around the corner waiting to reach out.
Sadly there wasn't. I had worked myself up into a tizzy over nothing, well almost nothing - a few ghosts.
But then it did its job - its a beautifully crafted story with impressive graphics which has been written by a small team and displays a lovely Welsh myth.
On the practical side I like the fact that, thrown into the game, your survival instincts hit in and right from the start you have to forage, gain access, find out whats happening - even the old chestnut - to switch the power on and light a fire. These touches drew me into the envinonment.
My only real criticism is that sometimes objects couldn't be picked up until they were needed in the game - but I'm not told that. I genuinely thought this was a bug, and perhaps an 'inner voice narration' - the 'No, that won't work' line you got in 7th Guest or the Tex Murphy games mightn't have been a bad idea, also a map to jump around the vast grounds.
But these are mere details. This is an impressive, pleasant and captivating game and one worth playing.
