In the interest of making my Lone Wanderer from Fallout 3 into my Courier in New Vegas, I realized the only thing I genuinely miss are a few of the quest-based perks that really embodied my character - a highly intelligent if not emotionally unstable scientist willing to experiment on himself routinely.
Ant Might / Ant Sight, Barkskin, Wired Reflexes, the Guru and Radiation perks from the Wasteland Survival Guide, hell, the bonus radiation resistance Booster Shot from The Pitt.
I found all the variables for these actually locked away neatly inside the New Vegas data files but my knowledge of perk creation is kind of.. limited. At best.
If someone could give me a crash course in this I'd love to release a package that allows you to add these old "experimental" favorites to your Courier if you, like me, wish you could have traveled from D.C. to California.
