"Best one so far....but...."
I liked this edition better than the former ones, it was somewhat easier, in the sense that you didn't have to waste time trying every piece of equipment to analyze the evidence because only a few that will work are offered to you for use each time. You also don't spend time hunting every little pixtel for evidence. You can still miss something, but not as easily as you could on the older games. What I did find to be a real drag was the length of time it takes for the game to load each new location. It seems to take forver to go from the lab, to the crime scene and right back again. I have a new computer which is quite fast, but yet, it still takes forever to load.

The cases are longer and they sort of tie together but in a way where you can us your past knowledge to help you solve them. I think UBIsoft did a great job with this game and I can't wait until the new one comes out in September.
I got this game for little or nothing either off of Amazon or Ebay, I forget which one, but it was well worth the price.

"And I wasn't even a fan of the show"
This game is great. I bought it for my mom who loves the show, but then started playing it and couldn't stop. The cases are the perfect lengh--challenging enough to take a few sit-downs, but not so long you get frustrated. There are three difficulty levels, and you can turn on or off various 'hints'. I had all the hints on and found it very rewarding. There are five cases to solve, and with each one I was guessing (usually wrongly) with great intensity who the perp was. The voice acting and 3d animation is great too; apparently the previous games were in 2d, but I can't imagine how that would work having seen how fun this dynamic is.
I had a little difficulty installing the game--it took three tries--on my windows vista computer, but now it works perfectly. The loading times between sites are only a few seconds, so you never get bored or anything. Of course the game isn't for tiny children, but from what I've seen of the show, if you let them watch that the game wouldn't be much of a shocker.
I can definitely see why fans of the show would enjoy this, and as a non-fan, I found it very fun as well.

"csi three dimensions of murder"
love csi, not crazy about the game. not very difficult. finished all cases relatively quickly. nancy drew mysteries were harder to solve. please come out with something more challenging!

"Game is great...if it runs"
When I loaded the game it wouldn't open. My computer is new (Nov 06) and I kept getting a security problem alert. I was able to open it from RUN: in the start box as long as I didn't open any other program before I opened the game. I emaied tech support and they told me to change the CSI.exe to CSI old and then download update from their site. I was in the middle of game 3 and since changing the exe to old it would never open again no matter what I did. So the game was a blast but I will not purchase another game made by UBISOFT.

"Long but awesome"
This game was wayyy longer than the previous two. There are more questions and evidence to collect which can make the game very time consuming. There were also some very interesting twist to the cases and the special effects were awesome. I believe this is the best one by far. But once again, the cases are quite long.
