Hi all. I was wondering, how much intelligence impacts on Xp. When weighing up which SPECIAL to focus on at the start of the game... it does seem tempting to negate a lot of other stats in order to level up quickly and allocate points to the others... or is it a very marginal difference?

From a regular super mutant kill, I gain 8 XP with 7 intelligence. I don't think difficulty affects this amount.

Someone out there with a low intelligence that can give a comparison value?

I believe I gain 25 xp from finding a new location as well.
