I'm sure this has been mentioned before, but I haven't seen an actual post on it. Sorry if I'm late to the party. I wasn't so much as interested by the perk details I already knew, but by the MAGAZINES!
So instead of giving a temporary bonus (NV), they seem to have their own perks related to them. For instance: their are 10 issues of Grognak the Barbarian (each with their own cover art, which is awesome) and each one you find raises the 'Barbarian Perk' by one, and the perk itself increases the critical damage of your melee weapons.
I have to say, this is a step up from previous magazine uses.
Hope you guys found this informative! What do you think each of the different magazines we are used to will do now? What perk, if any, will they effect? I for one, and excited to see how much this will actually effect gameplay!
