I absolutely love CSI and this game doesn't disappoint.
CSI original: the games were quite short but enjoyable, graphics not as good as they are on the wii games but it doesn't take away the enjoyment of playing.
CSI Dark Motives: I think the best game of the three, but then, i've not played Miami yet so I can't say for definite. The games are longer and more complex,could really get my teeth into them.
All in all, love it. And so cheap too, 1.26 is amazing!
