Sessions played (673,395) A "session" is a single instance of play, from game launch to quit. This shows the total number of sessions since June 10th. Games Completed (38.12%) This is the percentage of people who have completed the entire game since June 10th. The data shows people who played for at least an hour and saw the credits at the end of the game. Games Completed (38.12%) Our data indicates that while 42.05% of the players have reached the final map (as noted in the Highest Map Played graph below), only roughly half of those players have completed the game. This leads us to believe that either players are quitting before they see the credits, or there is a bug in how we collect this data. Average session time (0h 26m) The average length of time that a player played before quitting. This is calculated by dividing the total number of sessions played by the total recorded play time. Average total playtime (5h 01m) The average time that players have spent playing Half-Life 2: Episode Two, among players who have played at least one session. Average completion time (6h 26m) The average time it took to play the entire game. The data shows only people who played for at least an hour and saw the credits at the end of the game. Average completion time (6h 26m) This time to complete the game is very close to our target time, and is approximately what we observed during internal pre-release playtests of Episode Two. HDR enabled (76.41%) The percentage of players who had HDR enabled, among players with at least one game session recorded. HDR enabled (76.41%) This number coincides with the number of users who appear to be capable of running the Source engine with HDR turned on, according to the most recent Steam Hardware Survey.
