Everyone seems to go through their RPG books differently. Some people like to go through from the front cover to the back cover straight. Others will jump around, reading either the fluff or the mechanics first and then the rest later. Some don't even look through the book until they need to find something, they have the rules explained to them (or already know them) and just have the book for things like looking up feats or gear.
Hell, in the groups I am in around here, there are almost as many different ways to read the RPG books as we have people.
Personally, I tend to do a combination of two things. I usually will start reading from the beginning, but eventually I hit a point where I'm just not as interested in what is before me as I am in figuring something else out. At this point, I start skipping around. On the plus side, it means I usually learnt he system fairly fast, which is good if I am GMing. However, it also means that I tend to not look through some sections as thoroughly as others. I still have never really gone through the magic section in L5R for example.
So, how about you? How do you read your RPG books? Is there a specific reason why? Do you like the fluff and feel more than the mechanics? Or the other way around? When you do read a new RPG, what are you looking for?
