This book is horrible. For a start, it's not a Fallout roleplaying game, its a Fallout 4 mimic that supports role playing. Just before I continue, I wanna say I have nothing against Fallout 4, I hundreds of hours in it. The game tries to stick to the vibe of Fallout 4 to the point of which it shoots itself in the foot. The skills list is missing essential skills that need to exist, it looks like it belongs in a vido game, not a TTRPG. The 2d20 system initself is agressively meh, i didnt enjoy it but this is a review on this book not the system in general, but, its way too simole and just feels small. Also, as per standard with Modipheous, the editors are useless, at least in regards to explenations and layouts, however, I will admit that this is a gorgeous book. Like serious eye candy, but as much as I love the looks, its edited poorly and thease things cancel out. This game does nothing origional whatsoever in the Fallout universe, I already have hundreds of hours institute interaction, popegun use and crafting. If you've played Fallout 4 you do not need to own this book, if you have not, go buy that instead of this book. I hate this book so much, I paid like 30$ for it or something ridiculous, and am prob gonna delete it permanently from my library, just so I don't have to be reminded that it exists.
