I have been a fan of the books and the games for a few years and have finally decided to start collecting models for the tabletop game. I would like to go with the Horus Heresy models, but am completely unsure on what kind of rules work in relation to the difference between the 41 mil. marines and the 3 mil. marines as they are from two different rule books. Also, are the books worth the price? As for the models I want to know the pros and cons of making your own legion/chapter and what units would be good to start with, and if acrylic paints will work instead of model paint. Help?
