While the Horus Heresy setting can be more complex and involved than the standard Warhammer 40k universe, it is still an excellent option for beginners who are interested in exploring the rich history and lore of the setting. By starting with a Warhammer 40k starter set and gradually transitioning to the Horus Heresy, newcomers can build a strong foundation in the game while also enjoying the unique aspects of the Age of Darkness.
