This game has a good storyline which keeps the game interesting. The game is divided into two sections. In the first part you play the detective, interview witnesses and gather evidence. In the second part you conduct the court case (with a bit more investigation thrown in). You will learn about the American justice system in the course of play.
Some rough edges were apparent, the game froze a couple of times, necessitating rebooting. The game has a timer which limits the amount of things you can do between sections. There is a patch available which effectively slows the timer. The same patch also was required to enable the game to work under DirectX versions higher than 6. The graphics are not the best, but adequate for the game.
Summary - great game, good gameplay, pity about the technical side but most problems can be overcome. I've not seen the TV show, but it looks like it might be worth looking at judging from the game.
