This is just a poll to see how people approach a DLC when looking for swag.

I normally just loot the odd thing as I would when playing through the normal game but I make sure to save special DLC stuff like new weapons and clothes no matter how crap they are.

I lol'd at the last option.

I have the strange mind-set that if something doesn't respawn and is therefore finite in it's source I take every single instance I find just in-case I need it later - even though I will freely admit that I won't.

It's funny because in the game's beginning I'm pretty much the last option, if isn't nailed down, I take it. But as the game goes on and you acquire the armors, weapons and wealth you want, I start to select.
I mean, after a while we are pretty much rich, so you don't need to pick every wonderglue, scrap metal, scrap electronics, wrench and duct tape for crafting WRK, you can buy it from the Boomers or you can buy the materials from merchants and if you have Dead Money, you have an endless supply.
After this point I pick the ammunition and money an enemy is carring, that's all.

If I have the Jurry Rigging perk and his weapon serves for repairing mine I take, otherwise I leave it, even if it's an AMR.

I take all the new guns. All of them. Came out of Dead Money with six automatic rifles.

Everything else is on a one of each basis.

i usually grab everything......sell it later....i dont know why.....i already have a ton of caps

I take EVERYTHING in sight. I have unlimited carry weight so I don't need to worry about that..

I take anything that's interesting (maybe some decor for the SINK) and may be useful.

I rarely loot anything in Fallout games.
