If you enjoy spending hours fiddling with software that doesn't run properly, searching every possible website imaginable to help troubleshoot that software, and reading a 40 page PDF file hoping to find a morsel of useful information on installation, then Chessmaster is the game for you. A colossal waste of time. I have purchased many other games and had no trouble installing and running them, but this one is pure frustration. I managed to get a few false starts with this game which merely let me watch the introductory video that tells you how great the game is. Funny thing is, that's the only part of this software that worked. Now I get to find out how difficult they will make it for me to return it for a refund.
