Looking at the data by age reveals other interesting findings. Below is a chart that plots the correlations between each the content type ratings and age.

The graph below shows that older players are more likely to prefer solo content, while younger players are more likely to prefer high-stakes PvP and large-scale raids and PvP. We've seen this "hard-core" aspect of younger players in other places before.
