The dinosaur set on the 3D Green Marble board is stunning in 256 colours. Music and Sound Chessmaster 4000 lacks somewhat in the area of music. The onyl music is found in the option to loop playback a number of midi files that come with the game. These midi's are not poorly done, but I find this option pretty much useless as I can play my own music with a program running in the background. The sound however is very well done.
Sound effects play after every moves, with special sounds after castling, checking, capturing, etc.
In addition to the sound effects, there is a ton of speech in the game. I was very impressed by the function called Natural Language Advice. This makes the computer analyze your current situation, form a multi-move plan and present it in plain English by forming sentences from words found in its speech library. This cut and paste method is not seamless, however, it's still amazing and especially useful for younger or beginning chess players. Complaints Do not be fool by the relatively low minimum system requirements.
