Quick answer: Without error tracking, every failure your players hit on your deckbuilder is invisible to you, and most of them never report it, they just leave. Error tracking captures each failure automatically with a stack trace and full device context, turning silent churn into a fixable list ranked by impact. For an indie developer whose reputation lives on reviews, it is the difference between guessing and knowing, and it is not optional for a game you intend to keep.
Ask a developer who has shipped a few games what they would do differently, and error tracking comes up again and again. Not because it is exciting, it is not, but because the alternative, shipping a deckbuilder and hoping, turns out to be far more expensive than it looks. This post lays out the real argument for error tracking: not as a checkbox, but as the visibility that everything else, prioritization, fast fixes, good reviews, ultimately depends on.
The core of the argument
Strip away the details and the case for error tracking on a deckbuilder comes down to a single asymmetry. The failures that hurt you most are the ones you cannot see, because the players hitting them leave without a word. Tracking makes those failures visible; everything else, the prioritization, the faster fixes, the protected reviews, follows from that one change.
That is why this is not really a debate about tooling preferences. It is a choice between knowing and guessing. Once deckbuilder developers have seen the gap between the failures they assumed were happening and the ones actually happening, the question stops being whether error tracking is worth it and becomes how they ever shipped without it.
You cannot fix what you cannot see
Picture running any other piece of software with no idea when it failed. That is the default condition of a deckbuilder without error tracking. Players hit exceptions, sessions die, and you learn about almost none of it. Your own testing covers a thin slice of the hardware and situations your players actually inhabit, so the failures that matter most, the ones on devices you do not own and in states you never tried, are exactly the ones you never witness.
And the cost of that blindness compounds. Each day you ship without visibility, more players meet failures you will never hear about, and the damage to your reputation accrues silently. Deckbuilder developers who add error tracking almost always describe the same shock: the game they thought was stable was failing for a meaningful slice of their audience the whole time. You cannot manage what you cannot measure, and stability is no exception.
Most errors are never reported
It is tempting to treat the absence of complaints as evidence that the deckbuilder is healthy. It is not. Silence is not stability. The players hitting errors are not writing to you, they are walking away, and a quiet inbox can coexist with a serious problem that is bleeding your audience one uninstall at a time.
This is the heart of why automatic error tracking matters so much. It does not depend on the player choosing to act. The instant something fails, the report is captured and sent, whether the player would have bothered or not. A failure that thirty players hit and none reported becomes a single issue with a count of thirty, demanding your attention. Without automatic capture, that error does not exist in your world, even as it costs you players you never knew you had.
Reproduction stops being a guessing game
Every developer knows the special misery of a bug they cannot reproduce. A player swears the game broke; you try the obvious steps and everything works; the report stalls and the bug stays live. The root cause is almost always missing context, the specific device, the exact sequence of actions, the state the game was in. Error tracking captures all of that automatically, so the report arrives with the information you would otherwise have to extract painfully over a week of back-and-forth.
This turns reproduction from a frustrating guessing game into a guided one. You see the exact build, the device, the recent events, and the line that failed, and suddenly the bug that 'only happens for one player' is something you can trigger and fix on the first try. The time you save here is enormous, and for a small team that time is the scarcest resource you have.
Reputation is decided by the bugs you miss
Reviews are a lagging indicator of problems you should have caught much earlier. By the time a complaint about your deckbuilder appears in the store, the bug has already churned many silent players and is now actively deterring new ones. Error tracking moves you upstream of that, letting you fix the failure while it is still just data, before it ever hardens into a public, permanent review.
The cruelty of it is that great games still fail this way. A genuinely good game with a common crash gets review-bombed for the crash, not judged on its design. Players cannot appreciate the parts they never reach. Protecting stability with error tracking is how you make sure your game is judged on its merits rather than on a bug you could have fixed in an afternoon.
Treat it like source control
There is a persistent myth that error tracking is something you graduate to once your deckbuilder is bigger or more serious. In reality the earlier you add it, the more it pays off, because the early build is the one breaking most often and teaching you the most. Waiting until you 'need' it means flying blind through the exact period when visibility is most valuable.
Think of error tracking the way you think of source control: as basic infrastructure you would not seriously build without. It is not glamorous, players never see it directly, and it adds no feature to your game. What it adds is sight, the ability to know what is actually happening to your players instead of guessing. For any game you intend to maintain and stake your reputation on, that sight is not optional, and the cost of adding it early is trivially small.
Setting it up with Bugnet
This is exactly the workflow Bugnet is built for. Drop the SDK into your deckbuilder and every unhandled error is captured automatically, complete with stack trace, device, OS, and the recent actions that led up to it, so nothing breaks for a player without leaving you a trail. An in-game report button sits alongside it for the softer issues, the soft locks and confusing moments, that automatic capture alone would miss.
From there, Bugnet groups identical failures into a single ranked issue with a live count, so the bug hurting the most players is always at the top of your list. Device and custom-attribute filters let you isolate platform-specific problems in seconds, and crash data lives in the same dashboard as player-submitted reports, so you triage everything in one place. The result is the evidence-driven workflow this whole post is about, available almost immediately.
Where this leaves you
In the end the argument is not complicated. The failures that hurt a deckbuilder most are the ones you cannot see, error tracking makes them visible, and everything good follows from that visibility, faster fixes, better reviews, calmer launches, and a small team that punches above its weight. It is among the highest-leverage hours you can spend on your game, and almost no one who adds it regrets it. The only common regret is waiting too long to start.
The crashes you never hear about are the ones costing you most. Error tracking makes them visible while you still have time to act.
