How DeltaGRM Works
Transparency is one of my core values. If you're going to make decisions using my data, you deserve to understand where it comes from, how it's processed, and where its limitations are. I'll gladly explain my methodology, assumptions, and confidence levels.
"What I won't publish are the proprietary formulas and weighting systems I've developed to organize and compare that information. Think of it this way: The ingredients are public. The recipe is mine."
Collect
Every piece of information on DeltaGRM begins with publicly available data. I ethically collect information from sources that anyone can access, including public APIs, storefront metadata, historical records, and other openly available resources.
I do not purchase premium datasets from competitors or subscribe to paywalled services simply to republish their work. If I couldn't legally or ethically acquire it myself, it doesn't belong on DeltaGRM. As my database grows, I'm also building a historical archive of Steam pricing using publicly available information, Steam's own API, and historical snapshots to create a more complete picture of how games evolve over time.
Process
Raw numbers rarely tell the whole story. Revenue, for example, isn't published publicly by Steam. Any website claiming to know exact sales figures is making an estimate. I use the Boxleiter method as the foundation for my revenue estimates, calculating a probable sales range before determining a representative midpoint for display.
Like every estimation model, it has limitations. The Boxleiter method is generally accepted to have an accuracy range of approximately ±30%, depending on the title. To improve those estimates, I apply additional weighting and normalization based on publicly observable factors, including review behavior and other metadata. While these adjustments can improve consistency, no public estimation model can account for every variable.
Present
Information should answer questions—not create more of them. Instead of overwhelming you with spreadsheets, I organize data into pages, comparisons, rankings, summaries, and visual indicators that help reveal trends at a glance.
Whether you're researching a Steam genre, evaluating publishers, or comparing similar titles, my goal is always the same: Spend less time searching. Spend more time building.
Improve
DeltaGRM is a living project. Steam changes every day, and so will I. New games launch. Prices change. Developers grow. Markets evolve. My job is to continue improving the database alongside the industry.
I'm currently expanding my historical pricing database using publicly available information, allowing me to provide richer context around game pricing over time. Today, I don't track every sale, discount, or free promotion—but those are features I'm interested in exploring as the platform matures.
Variables Excluded from Public Estimation Models
Because of these factors, all revenue figures should be viewed as informed estimates rather than audited financial statements. Additionally, all estimated revenue displayed on DeltaGRM represents gross revenue before taxes. A title showing an estimated $200 million in revenue has not necessarily generated $200 million in profit—or even $200 million after platform fees and local taxation. As development continues, I'm implementing additional calculations, including estimated platform deductions and net revenue projections, to provide even more context. Once my core systems are complete and stable, community feedback will play a much larger role in determining what comes next: bug reports, feature requests, new metrics, and workflow improvements. If it helps developers make better decisions, I want to hear about it.
How DeltaGRM Stays Free
I believe information that is free to acquire should be free to access. That means I don't sell subscriptions to my database, and I don't lock features behind recurring paywalls. Instead, DeltaGRM is supported through services that complement the platform rather than restrict it.
Community Support
If you find value in DeltaGRM and want to help me continue building it, you can support the project through Patreon for as little as $3 per month. Supporters receive community perks, recognition, and opportunities to help guide future development—but the data itself remains free for everyone.
Promotions
I offer featured placement across DeltaGRM for developers, studios, and creators who want additional visibility. Whether you're launching a game, showcasing your portfolio, or promoting a Kickstarter campaign, you can reserve space on my platform through fixed weekly, monthly, or quarterly placements. Promotions help fund the platform while introducing my visitors to projects they may have otherwise missed.
Corporate Sponsorships
I'm actively looking for companies that want to reach a global audience of game developers, studios, journalists, and creators. If your product or service provides value to the game development community, I'd love to discuss a partnership.
My Promise
I'll never claim my estimates are perfect. I'll never pretend my methodology is infallible. And I'll never charge you a subscription to access information that was already freely available.
DeltaGRM exists because I believe the game industry deserves tools that are transparent, accessible, and built with the community—not against it. Industry knowledge belongs to everyone.
