Joe LaRue of The Koalition writes: In the World of Darkness series, the first game that comes to mind is Vampire: The Masquerade Bloodlines. This is a modern-day world where you learn about vampires within the first few hours of gameplay. You learn everything from what they can and cant do to their society and how the world looks at them. So, for anyone new to the World of Darkness and the Vampire play style, it gives you stepping stones to follow and helps you to better understand the world and its people. In Werewolf: The Apocalypse -Earthblood, it appears that you must already be familiar with this world or you will be lost in translation when you start playing.
