I've yet to play a game where it wasn't more beneficial to take all and ask questions later. Everything in a game is worth something to someone, even if it's just lowly vendor trash. With inventory sorting being ever the more sophisticated now, it's easier to sort junk and low-value items and dump them if I can't reach a vendor. If it's useable in crafting, I'll stick it in the generous crafting storage the game will have if the developers know what's good for their knees.
