Telltale Games, developer of the episodic Bone games and the (drool) soon-to-be-released 3D Sam and Max game, recently posted that a new sequel in the CSI series, CSI: 3 Dimensions of Murder is now available for purchase, along with a download-able demo of a sample case from the game.

The game appears to be receiving some fairly good reviews for its excellent voice acting, good 3D crime scene graphics, and immersive gameplay. For $30, you should be able to squeeze about 8-10 hours of solid gameplay out of this one, which might be a slightly better dollar-per-hour ratio than the similarly episodic Half Life 2: Episode 1 (although who can really say, when it comes to the dollar-per-fun ratio). Check out the demo and the site in the link below.
