Do anybody know where I will be able to find CSI games and similar games like this.

My partner and I bought a CSI game... over a year ago. It is a board game though, I don't know if that's what you're meaning or video game. I think we got it at a Shopper's, so you should basically find it anywhere. It was good, was. Once you've played every path, you know all the answers.

Try ebay:

csi, Games, Accessories items on eBay.com

But hold out for the small sellers. It looks like it's mostly be controlled by a bunch of big sellers with too-high prices and too-high shipping.

Or Amazon if you don't like eBay but they're even more expensive:

Amazon.com: csi - Amazon.com: Software

As for similar, do you mean very similar? There's also a Law & Order series. Or do you just mean solve-it mystery type things cause there's also the Nancy Drew series. Or do you just like solving puzzles? Cause there's lots and lots of those, but I haven't played the CSI's so I don't know exactly what they're like.
