The Psychology Behind Why We Buy Games We Never Play
Pedro Faiole·
Here is a number worth sitting with: according to data from GameDiscoverCo, the median Steam user has left 51.5% of their library completely unplayed. Not "haven't gotten to yet." Never launched. Untouched from the moment the purchase went through.
A separate estimate puts the total value of unplayed games sitting in Steam libraries at roughly $19 billion. Nineteen billion dollars of entertainment, purchased and forgotten.
If you feel called out, you're in very good company. The question worth asking is not "why is my backlog so big?" The more interesting question is: why do we keep buying games we know, on some level, we probably won't play? The answer turns out to be less about discipline and more about how our brains are wired — and how the games industry has gotten very good at using that wiring against us.
Your Brain Doesn't Want the Game. It Wants the Feeling of Getting It.
The most counterintuitive piece of this puzzle comes from neuroscience. Most people assume that dopamine — the brain's reward chemical — fires when you receive something good. Turns out, that's not quite right.
Research by neuroscientist Robert Sapolsky, studying reward behavior in primates, found that dopamine releases most strongly during anticipation of a reward, not when the reward arrives. In his experiments, monkeys pressing a lever for food treats showed peak dopamine during the moment of expectation, well before the treat appeared. And crucially, the effect was strongest when rewards were unpredictable. When treats came 100% of the time, dopamine was moderate. When there was only a 50/50 chance, dopamine roughly doubled.
What this means for your gaming backlog: the act of browsing games on sale, imagining playing them, adding them to cart, and clicking "buy" is neurologically rewarding in its own right. The anticipation phase is the high. Once the game sits in your library, the anticipation is over, and so is the dopamine hit. Playing it would reset the cycle, but that requires effort, time, and focus. Buying the next thing is frictionless.
This is not a character flaw. It is a feature of how human cognition evolved, and the games marketplace is extraordinarily well-designed to exploit it.
The FOMO Machine
The second force at work is fear of missing out, and digital storefronts have refined it into an art form.
Research documented by game psychologist Jamie Madigan explains what he calls the "scarcity effect": when people perceive something as limited in availability, they assign it higher value and feel urgency to acquire it. Time-limited sales, countdown timers, and "only 2 left at this price" labels are all deliberate applications of this effect.
Steam seasonal sales, PlayStation Store flash deals, and Xbox sales with daily-rotating discounts are not designed to help you find the right game at the right time. They're designed to trigger the feeling that you might miss something irreplaceable. A 2025 analysis from Vaulted Games found that 55% of shoppers report feeling they must buy immediately when a deal might disappear — even when they have no clear plan to actually use what they're buying.
The discount also changes the way you mentally account for the purchase. A game you bought for $3.99 during a sale doesn't feel like $3.99. It feels like you saved $15.99. The perceived value is amplified. The actual commitment to your time (which is the real cost of any game) doesn't get discounted at all.
The Ownership Illusion
There's a related trap worth naming: the feeling that owning a game and playing a game are meaningfully connected. They aren't, but the brain blurs them together.
When you add a game to your library, you gain access. That access feels like potential. And potential is pleasant to hold. You might play it this weekend. You might play it when you finish your current game. You might play it during the holidays. The game is there whenever you want it.
This illusion of "I could" functions like actually doing the thing. Joshua Becker, writing about consumer psychology, notes that people often buy things not because they plan to use them, but because ownership provides psychological security. The game in your library represents a possible good time, and possible good times are comforting even when they never materialize.
The result is a library that grows as a form of emotional insurance. Every unplayed game is a little promise to yourself about future enjoyment.

The Paradox of Choice (Or Why 1,200 Discounted Games Is Terrible)
Here's a cruel irony: the bigger your backlog gets, the harder it is to actually start playing anything.
This is why a large backlog can paradoxically result in less playing, not more. The choice becomes so loaded with potential regret that the path of least resistance is to browse a bit, feel overwhelmed, and not play anything. Or buy something new, which at least produces that familiar dopamine hit without requiring a commitment.
What the backlog promises
What it actually delivers
Easy choices ("just pick something")
Paralysis ("too many options")
Guaranteed entertainment
Pressure to pick "correctly"
Freedom from boredom
Anxiety about wasted purchases
A sense of abundance
A sense of obligation
How Platform Design Makes It Worse
Game distribution platforms have multiple interlocking features that encourage accumulation over play.
Wishlists as FOMO traps. Adding a game to your wishlist trains the platform to notify you when that game goes on sale. The wishlist was supposed to be a memory tool. In practice, it's a queued purchase trigger. You add games in moments of interest, then get hit with a nudge months later when you may not even remember why you wanted it.
Bundles. The bundle model is brilliantly designed to generate backlog. You want three games in a ten-game bundle. The bundle is cheaper than buying those three games individually. You buy the bundle. You now "own" seven games you didn't choose and almost certainly won't play. Each of them takes up mental real estate, contributing to the weight of the backlog without ever having been desired in the first place.
Social proof. Friend activity, review scores, and streamer endorsements all generate purchasing pressure independent of whether you have time for the game. When twelve people in your network are playing something, not buying it feels like exclusion. Buying it feels like participation, even if you never actually launch it.
The Sunk Cost That Keeps Growing
Once a large library exists, a new psychological mechanism kicks in: the sunk cost effect.
The sunk cost fallacy is the tendency to factor past investments into current decisions, even when those past investments are irrecoverable. In gaming terms: you've already spent hundreds of dollars on games you haven't played, so buying one more at $4.99 feels trivial relative to the total. The existing backlog makes each new addition look cheap by comparison.
Researchers have documented this effect as a driver of continued acquisition even when people are rationally aware they already own more than they can consume. The backlog doesn't feel like a reason to stop buying. It becomes a context that makes more buying feel proportionally less significant.
Breaking the Cycle: What Actually Works
None of this means you're helpless. The first thing that helps is just naming what's happening. When you feel the urge to buy something during a sale, asking "am I buying this to play it or to own it?" is genuinely useful friction.
A few practical approaches that address the specific mechanisms above:
Add friction before purchase. Put games in your cart and wait 24 hours before completing the transaction. The dopamine of anticipation doesn't require you to actually complete the purchase.
Use wishlists differently. Treat your wishlist as a staging area for genuinely high-priority games, not a place to park everything interesting. If a game's been on your wishlist for two years, ask whether you're buying for potential or because you'll actually play it.
Set a one-in-one-out rule. For every game you add to your library, pick one already there and either commit to playing it next or remove it. This forces honest accounting.
Track what you actually play. When you have a record of what you've completed versus what you've bought and never touched, the gap becomes visible and uncomfortable in a useful way.
That last point is where building a real gaming log on The EndWiki changes how you buy. When you can see your actual play history alongside your library, the distance between "games owned" and "games played" becomes concrete rather than abstract. It's a lot harder to buy your 14th unplayed RPG when you can see that you've finished exactly two RPGs in the last year.
The Thing Worth Tracking
Backlog psychology is one part of a bigger picture covered in depth on the Backlog Mastery hub. But the starting point for any of it is the same: you need visibility into what you actually play, not just what you own.
The EndWiki gives you that. Log the games you've beaten, track what's actively in progress, and keep a wishlist that's separate from your "bought but untouched" pile. When you can see your real gaming history clearly, you start buying with more intention, because you're comparing new purchases against actual evidence about what you finish.
A library you understand is one you can actually manage. A library full of invisible potential is just $19 billion in dreams.
