There are no where near as much skill books in fnv than f3, so you don't get too overpowered
This is true, but if you take the skill book perk early like I have you gain x4 on each book read so you don't actually need that many to boost. So far i've found around 6 to read, 2 that need stealing from dodgy locations that I have not worked out yet as I don't want to anger the owner. Neutral Good character.
