The way to do this is to head straight to the strip at the start, after looting the generous doc's home so you can have some caps to start with, and amass a fortune through blackjack (or at least enough to get the intelligence implant.) This should go quickly and easily, considering the 9 starting luck! You'd have to start with the Atomic Wrangler in Freeside so you can have enough caps for the credit check into the strip. I took, and recommend, the traits: Built to Destroy and Fast Shot. Charisma's effect of 'nerve' seems lackluster compared to everything else, but it is not difficult to boost by consumables either, if you feel your companions are in need of it. That's right, 1 strength! The melee damage benefit of strength is pointless here, you can have companions lug your stuff around, and strength boosting foods are incredibly easy to come by, to cover weapon strength requirements. The others (with the exception of Sneak which caps at 97 without a Stealth Boy, and Survival since maxing it is mostly unnecessary and you'll still be able to cook what you want,) can be enhanced to 100, and by later levels, the dependency on food and chems for them will reduce. This build gets natural 100s in Energy Weapons, Explosives, and Guns. So melee can still play a role for this build without spending any points on the respective skills.) Special Unarmed moves like Ranger Takedown and Khan Trick can still be acquired and be used for combat utility. Melee related perks have demanding requirements that my methods don't pretend to meet, and without the perks to make your melee useful and dangerous, why bother? ( Pyromaniac will be available, though, to enhance the Shishkebab, it will just swing slower without meeting the wield requirements, and that would be irrelevant if you use melee weapons for sneak attacks.

This is a pre-DLC NV character build that I aimed for optimal ranged combat, while being adept at non-combat skills, and also having a wide variety of perks to be available for customization.

There doesn't seem to be an equivalent character build thread for New Vegas as there is for FO3 ( Forum:Fallout 3 character builds), so I'll try to get things started on this!
