Support PlayTracker on Patreon to unlock access to more charts, historical data (coming soon), and additional tools like the comparison tool which lets you see overlap between games. Your support will speed up development of future features!

Overlap

The overlap graph shows a venn diagram of how the audiences of the game you are viewing and the game you have set to compare overlap. There are three important values here - the absolute overlap which is a percentage of the combined audiences of both games, and then the percentages of overlap for both games individually. So for example, if game A has 20 players and game B has 30 players with 5 players having both, the absolute overlap will be 10%.

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).

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).
