How does PlayTracker Insight work and is it accurate?
PlayTracker Insight uses platform gathers public data from gamers around the world in a random sample and extrapolates that data to estimate total values.
PlayTracker correlates that random data with internal data from PlayTracker users to get more detailed information, for example the "Achievements over time" graph, which shows how a game has fared over the years.
For every game, you can click the information button next to the estimate to open up detailed margin of error and confidence data. It is, however, still an estimate, and can be off due to various factors. This is no different to other similar services.
The sample grows every day as PlayTracker crawls new accounts. The current sample is updated on a cycle lasting around 4-5 days, meaning data for a game's launch weekend should be fully accurate by the end of the next week.
PlayTracker started gathering Steam data in early March 2019, and has expanded to other platforms since.
What is the "Windows" platform and how are you getting this data?
The Windows platforms uses data provided via the XBOX API for all played games a Windows 10 user with a public profile has played. This includes all launchers like Steam, Origin, EGS, uPlay, and more - but some games are missing and others have multiple entries, so we encourage you to browse this data with care as there may be inaccuracies.
We cannot differentiate between different launchers within the Windows data itself. You can, however, correlate this data with other data we have to make conclusions. For example, if a game is available on Steam, deducting its Steam figure from its Windows figure will give you an estimate of how well the game did outside of Steam.

Why are you giving everyone access to Steam data?
After Steam changed profiles to be private by default, SteamSpy locked most useful data and graphs behind a paywall because a lot of things were broken and needed fixing. I disagree with this philosophy and believe it will be easier to fix and improve Insight with the help of the public, not just for Steam but all the supported platforms. Furthermore, it's simply useful and fun to browse data, and I think it can survive off Patreon donations.
If there are no ads, how will the site survive?
Patreon donations encouraged by unlocking new features. New features for everyone via funding goals and exclusive convenience/cosmetic/advanced features for supporters via benefits. For example a convenience feature is the ability to compare data between games on the same graph and see the overlap between two games, a cosmetic feature will be the ability to change the highlight color on your PlayTracker profile and an advanced feature will be more detail in the existing graphs like monthly datapoints instead of yearly for the "Achievements over time" graph.
Who are you and why are you spending your time on this?
I'm Marijan and PlayTracker was originally the graduate project for my bachelor's degree in multimedia computer engineering. Back then, it was just a profile site. It got such praise from my peers and professors, that I decided to take it public and continue working on it in my free time, for fun and to learn new skills and hone my existing ones. I opened the Patreon hoping that eventually it will make enough in donations to cover the cost of hosting (almost there) and maybe eventually enough for it to replace my side gigs and allow me to spend more time on it.
My day-job pays the bills, so I do not feel pressured for PlayTracker to be profitable and have been able to keep it up and develop it further for almost a year now while technically running a loss every month. It's like a Netflix subscription at this point - it costs me about 10€ a month and takes up a lot of my time, but it's enjoyable so I'm cool with it.

What is "popularity"?
Popularity is a metric derived from the number of people that own a game and the number of people that are actively (in the past two weeks) playing it. The active players have a 4x multiplier, which evens the two numbers out in importance. I tested various popularity algorithm and found this one to be the best.
Can I use your data for my own thing?
Yes. Be it in an article or elsewhere, you may use PlayTracker Insight data, article text, and article cover images. Please give credit if it is not too inconvenient, and consider donating on Patreon. Feel free to contact me on this topic if needed.
