Recommended for hard-core fans of backgammon with friends on X-Box Live.
Graphics: These are passable for this pricepoint - you get a choice of backgrounds and boards/pieces/dice which is about all I expect. A nice touch is the uneven way the pieces lines up when you move them off the board.
Sound: Horribly dull on the effects. Some of the background themes do give you some ambient sound to give you a relaxing atmosphere - or you could just play some music of your choice like I do.
Value: Considering it only goes for $5, I suppose you can't expect any better. Maximize the value by using multiplayer. Most of the achievements are easy to reach - you can get 4 of them in the first hour or so and 10 of them in 3-4 sessions.
Final Thoughts: The Backgammon game on Microsoft's Zone.com is superior to this in every way and offers much better chance of finding a good opponent. I'm hoping Microsoft ports some of those games to X-Box one day or a company like Hoyle makes a X-Box version that is cheap like this one, but keeping the gameplay.
