Fo3 DLCs introduced ammo benches, chinese stealth armor, new weapon styles and some tougher opponents. All of which were strong enough additions to make it into vanilla NV.

What are some elements of the Fo:NV DLCs that you liked the most?

I enjoyed the poisonous clouds, hologram security, radios, .45 caliber firearms, new plants/ ingredients, throwable hatchets, new companion perks (Walking Chalk's, specifically.), ability to fill empty bottles with water, energy styled melee weapons, origins of wasteland creatures, robot scorpions, a valid purpose for hoarding clip boards and mugs, giant robot animals in general, meaner deathclaws, armor that actually looks jury-rigged, caves made of toppled buildings, satchel charges, and locations that open up in the base map solely because of actions done within the DLC world.

One thing I didn't particularly like, but wasn't too upset about was being able to just turn back around and go home prematurely, such as in LR.

One thing I absolutely was not fond of was not being able to get back to the Sierra Madre post DLC.

What are you into?
