Currently doing a 'loud and proud' playthrough of F:NV. My personal rules:
* No stealth armor types, including not using the third level of Stealth in Signature Armor mod
* No silenced or scoped weapons, and definitely no silenced AND scoped weapons.
* Not permitted to put points into the Stealth skill or read any Chinese Spec Ops Manuals, until ALL other skills have been capped
Currently running around with the Survivalist's Rifle and a grenade rifle. REALLY tempted to try out FIDO, though.
I'm actually really tempted, this time, to use the Elite Riot Gear instead of the Vault Trenchcoat from AWOP, because it isn't Light armor that still grants +5 Crit mod. Be a nice change of pace.
