Well, Marco, it depends on how much you think you would use it. I got a copy, and I found it to be full of wonderful concept and CG art, not to mention nice stills from the various games. I use it a lot as reference material for my own art, and it has served me well. However, if you think you'd just get it, look at the pretty pictures, and then put it away and let it collect dust, then I wouldn't recommend it. Of course, if you're a rabid Oddworld fan, go for it.
