You can also do area loot for minions and traditional for harder enemies, so you won't lose the experience of each enemy having on them the equipment they used in battle. Or you could only area loot money and consumables and leave minion equipment on their bodies.
It's an option, but you have to consider the potential for confusion, you might get players overlooking an important drop in a pile of carcasses.
Still, I think the real potential for this discussion isn't in videogames, but in tabletop. Just imagine it...
"Nanoc cleaves the last goblin in twain, the party is victorious."
"Ok, we search the bodies."
"Sure, which one?"
"All of 'em, duh!"
"That's not how this works. I mean, you don't just enter a dungeon and declare you disable
all the traps, now do you?"
"Fine, uh, left to right, I search the first goblin."
"You find a goblin axe and two gold pieces."
"Okay, now I search the second goblin."
"You find a goblin axe and two gold pieces."
"Third goblin, lemme guess, a goblin axe and two gold pieces?"
"Correct."
"Okay, fuck this, you wouldn't have us search each one of the twelve goblin corpses if there weren't
something worth having!"
"Would you like to roll an investigation check?"
"
Please! Look, I rolled a sixteen!"
"On which goblin corpse?"
"Are you serious?! Even with a roll? Whatever, this one, the one I was looking at already!"
"You redouble your efforts on the third goblin corpse, and as you turn him over, you catch the sight of something glittering up his backside. You pull a small garnet out of the dead goblin's asshole."
"Great. Fantastic. I go back to investigate the second goblin. I rolled a twelve."
"You go elbow deep into the second goblin but find nothing more."
"Next. Rolled fourteen."
"You thoroughly search this goblin corpse before you realise you've already searched this body and looted his ass garnet."
"No, I meant next as in... You know what? Nevermind. We leave the dead goblins and move further into the dungeon."
"... Are you sure you don't want to search the other ten dead goblin assholes?"
