In Part 1 of this series on the psychology of Diablo III loot I talked about how the anchoring effect can affect our estimates of value for auction house items. In Part 2, I described how the availability heuristic can trick us into thinking that epic item drops are more common than they are. In this part, let’s look at the interaction between the auction houses and loot drops, including a suggestion on how to reclaim some of the fun of the loot drop.
Instead of Tristram, let’s head to Sweden to begin. Wolfram Schultz was working there as a neuropsychologist studying Parkinson’s disease in lab monkeys when he almost accidentally started a line of research that ultimately suggests a way that Blizzard could encourage us to keep grinding for new loot. Schultz’s research involved dopamine and dopamine receptors in the brain. Dopamine is a chemical that’s released when we encounter something pleasurable, like a piece of fruit or a Legendary Mighty Weapon for our Barbarian. The chemical is hugely important for learned behavior and motivation to persist in a task, since when it’s released certain brain cells go bananas and make us feel good. Maybe even euphoric.
What this means is that dopamine receptors are part of a system that’s about pattern recognition and figuring out how to get more good things out of life. Schultz and his colleagues discovered that presenting a lab monkey with a bit of fruit caused the creature’s dopamine neurons to light up. They also discovered that when they repeatedly preceded the treat with a light or a sound, the neurons would start to fire when the monkey saw the light or heard the sound, but then remain relatively inactive when the fruit showed up. The system they had discovered was, at its core, about anticipation and trying to predict rewards based on what was happening in the environment.
What’s more, it turns out that unpredicted gushes of dopamine really get us fired up. This is because unexpected dopamine rushes highlight failures in our predictive system, and it’s a system that’s designed to help us figure out why we didn’t see life’s good things coming and thus how to find them again in the future. This is why the random nature of loot drops in many games is so effective at getting us to keep playing: it capitalizes on our brain’s attempts to predict the unpredictable. (See here for more on dopamine and loot drops.)
Loot drops were indisputably core to the Diablo and Diablo II experience for all these reasons. Hearing the little “ting!” sound and seeing the beautiful, colored text indicating that a unique item had dropped produced a rush that every player looked forward to.
Only, not so much with Diablo III.
The reason is that the auction house is actually a FAR more effective but much more predictable way of finding better gear for your character than hoping for good loot drops from fallen enemies or treasure chests. In my experience it was super easy to buy equipment so good that the magical “ting!” sound soon lost its effect because the loot that dropped was no longer a reward. It was just gold in a slightly more inconvenient form, destined to be sold to a vendor or at best on the auction house for a little more. In effect, the auction house system excised the entire dopamine rush, loot drop appeal of the game.1
I suspect that the execs from Blizzard are too busy cackling and having money fights with the cuts that the company takes from real money auction house transactions to care, but this seems like a huge part of the game’s core appeal is now lost. I think there’s some middle ground, though, which is why I think the game should have a class of super items that are bind on equip.
In MMO parlance, “bind on pickup” or “BoP” items are treasures that bind to your character’s account once they’re equipped. This means they can’t be given away, sold, or otherwise transferred. You can just equip them, break them down for crafting materials, or just sit there and stare at them in your inventory. Finding a really good, color-coded item that’s BoP would restore some of that “ting!” feeling and dopamine rush, because it will be something that you won’t be able find on the auction house. Making the best items in the game BoP would go a long way towards creating those familiar dopamine rushes because they would signal a clear and strong reward, but even making them run the full range of quality would probably still work, since seeing one drop would signal the tantalizing possibility of something otherwise unobtainable. Suddenly, the loot drop would be back, baby.
So there you have it: three suggestions for tweaking Diablo III loot based on psychology. If you’re a game designer I’d love to hear your thoughts on these, especially if you’ve experimented with anything similar.
Done? You can go back to go back to Part 1 about anchoring in the auction house, or back to Part 2 about the availability heuristic. Finally, there’s a bonus part 4 about the effect of item history on auction house prices.

Problem solved: the marketplace has evolved so that the “degenerate gamblers unwilling to do steady work for steady income” crowd can now buy their high. 🙂
It is more interesting economics than psychology to discuss the implications if a 1/500 drop item is worth 1000+ times the average and the “1%ers” drive the market. Even if the economic value is positive, my guess is there is not a lot of casual fun or dopamine for payoffs that are in the once or twice a month range.
Expanding upon my previous comment: people play negative-sum slot machines in a casino to enjoy the thrill of winning. People also but one in 60 million lottery tickets. But since even they have to understand that after a lifetime of lottery tickets, they will probably never even have a friend of a friend who won. Yet they buy lottery tickets. Can someone who grinds 100 hours for a chance at a great weapon, or buys a lottery ticket, be explained by dopamine? Is there an anticipating-future-dopamine high?
Isn’t this “OMG D3 is not D2” contretemps really about forum warriors though? The most casual players don’t use and may not have found the AH. Nor are they likely to post about a video game. So they get their usual/D2 dopamine rushes. The least casual would tend to like things that add a new dimension to the complexity? In between …
Huh, cool link. Thanks!
The number of people who use and ignore the AHs seems to be all over the place. I’ve talked to veteran gamers who haven’t bothered, and I’ve heard from people who never played a Diablo game before who went straight for it.
My monk has now 100h+ played. i’ve been farming inferno for some time now and haven’t found any upgrade yet. With my dropluck I’m pretty much forced to use the AH since gear is progress in D3.
On the other hand a friend of mine was on his first Inferno farming run and found a 800dps fist weapon that was a huge upgrade for me.
It’s just not as rewarding to grind to slowly see your gold rising until you can afford an item. And then repeat.
I think that’s pretty much the same as in WoW when the started to introduce all the different points. It’s suddenly no more the dopamine rush every time I killed when killing Illidan for the offhand. Suddenly it was a boring grind and the only skill was maximizing your points gained per week.
And the same thing is true for D3. What I do and what the designers thought people will do, playing acts over and over again to get loot is suddenly the most unefficient form to progress. We all should just grind for gold to get our items from the AH. And that’s boring as hell.
So my “quick fix” would be to overhaul the crafting system. You can easily come up with a solution that factors in the randomness the game is based on without being totally frustrated. Currently it’s: get-> shitloads of mats and gold -> craft -> be frustrated because you just got crap items
What I really would like to see is that you can extract certain (random) attributes from items and if you use those “essences” will put that attribute on that item. The more essences you use for crafting the higher is the chance, that you get a really high value for that stat.
Suddenly all the blue items noone needs get a value again. You get the dopamine rush when you find it (“finally an item with life on hit”) and you get the dopamine rush when you manage to extract it (“Yeah, i got an essence of life on hit”)
poor blizzard.. spending millions of dollars on their games and always forget to ask me 😉

One thing I really miss from Diablo 2 is the gem-drop ‘ting!’ noise. Gems drop soundlessly now, and the ‘ting!’ is reserved for the sort of gear I’m just going to vendor anyway. D3 just doesn’t stimulate the loot senses.
you have to use the AH because it’s in blizzard’s interest for you to do so. the drop rates are purposefully too difficulty to effectively itemize your character without it. the entire game was designed to feed the AH with hopes that people will use the RMAH because blizz can make more money from it.
i have a bigger problem with 4 difficulty levels making up for a lack of content. why not make more content with 3 well refined difficulties? it’s an entirely different game once you get to inferno and the presentation to the user is poor at best.
the only drops you hear in this game are $.

Нi there, this ωeеκend is fastidious fог mе, because thiѕ time i

pаragraph here at my house.
I think you make some very good points in you’re articles. I personally stopped playing Diablo 3 because I did not get the sense of progress or satisfaction anymore.
And to break that down, i think games (especially games like Diablo or MMO’s) need to make players wonder “What’s coming next”. The not knowing what’s next and what you might discover or find (with loot drops i.e.) is something that keeps players motivated and eager to play on.
I personally think that Diablo III has to much transparency, the Auction House is something that greatly contributes to that transparency. This means players are more aware of the things going on ‘under the hood’ rather than feeling a sense of immersion in the game world.
When you discover the boundaries and the mechanics of a game as a player, you are no longer immersed as much, and with people constantly thinking about the AH and grinding Acts over and over again, they are constantly occupied with the ‘Meta Game’. Wich means they feel less connected with their character and the world that the character is in. And this results I think in the fact that you get less involved and therefore less satisfaction with progress or good loot drops.
This personally is very much so the reason why I don’t play Diablo III anymore. While I play I am constantly aware of all the mechanics that Blizzard has designed to keep me playing and spending real money on the Auction House. Actually might be the same reason I don’t like Casino’s as well 😉
I admit i love video games and I know im addicted and from what i am reading from all the comments i think its time for me to withdraw from all the games. I feel bad my son mite miss out on the real world since he is starting to love video games at such an early age. Thank you for giving me some insightful ideas.

My usual fallback for so many great ideas has a good one here too, that I’ve never seen in any major current title – Nethack’s named items. Nearly all of the loot drops are random (but plentiful) in NH, and one who hasn’t played much or hasn’t done much research would probably just go through the game with whatever was dropped, which would be fine. However, if you go to the trouble of sacrificing mob corpses on co-aligned altars, you can get your god to give you a named weapon with much more power. I think this would be a lot less compelling in a multiplayer game (although from the story perspective it could add a lot), but in a single-player game this kind of thing could add a lot of dimension, especially if the concept was carried through more than just a single item.
