The popularity of this game is shifting rapidly. Please keep in mind that PlayTracker Insight can take up to a week to reflect real-world shifts in ownership for this platform.
This game is so extremely popular that it extends beyond PlayTrackers's reliable range, data on this page is less reliable than usual.
Yearly achievement activity
The years achievement activity graph shows how the total achievements earned in a game are spread out over time, divided by years. It uses internal PlayTracker user data (n=~13000) and is displayed as a relative percentage of all achievements earned.
Monthly achievement activity
The monthly achievement activity graph shows how the total achievements earned in a game are spread out over time, divided by months. It uses internal PlayTracker user data (n=~13000) and is displayed as a relative percentage of all achievements earned.
New users over time
The new users over time graph shows the rate at which a game reached its current ownerbase using the time when a user earned their first achievement. It is a very rough approximation of lifetime sales. It uses internal PlayTracker user data (n=~13000) and is displayed as a relative percentage of all owners.
User interaction
The user interaction graph shows interactivity data with up to three values.
The first is "Played" which shows how many players have launched the game at least once. The second is "Active" which shows how many players have recently (2 weeks) launched the game. The last is "Perfected" and shows how many players have completed all the achievements for this game, provided the game has achievement support (otherwise this value will not show).
All three values are X% out of 100% where 100% are the total owners of the game. "Played" and "Active" percentages are calculated from Insight data (n=~500000) while "Perfected" is calculated from PlayTracker user data (n=~13000).

Concurrent players
The concurrent players graph shows how many players were playing a game at a given time, sampled from Steam. If only a date is given, it was a point in time on that date, not a peak or a sum of players. No internal PlayTracker data is used.
Playtime distribution
The playtime distribution graph showcases the distribution of users according to their total playtime, capping out at 100. The maximum number of hours shown includes everything above itself.
Popularity over time
The popularity over time graph shows PlayTracker's own "Popularity" metric for a game over time. "Popularity" is calculated from values like total owners, active owners, concurrent players, and more. An active owner is valued much higher than an inactive owner in "Popularity" calculation. It scales linearly - there are no diminishing returns.
Geography
The Geography chart shows how popular a game is in countries where there is enough data available while adjusting for the number of users from that country. So, for example, if players from a country equal 2% of our total userbase, but players from that country that play this game are 3% of that game's userbase, the relative popularity score for that country will be 1.5. Also states absolute percentage of players from that country for that game. Uses Insight data (n=~500000).
