While looking at the data I stumbled upon some interesting extremes: the longest gap between two games of an account in ZK is 11 years
[GJL]azaremoth !!! (there are 27 players with a gap larger than 8 year)
Overall here are some graphs with the largest gaps between two games of an account. First graph is with gaps larger than 1 year (so we have thousands of players that have a 1 year gap), second graph is just a "zoom" in the first, with gaps larger than 3 years (even more dedicated people!)
My personal largest gap was around 6 months.
