I know this website has topics for leaderboard. But the feature should be to have a leaderboard in the game. In the menu screen, it will rank people’s usernames and you can organise by: top xp, top flight hours, top landings, top ratio, etc. You press the button to choose which statistic to use to organise. There is a second button to choose all time or last 90 days. If some people do not have a username then their name can be “Unknown”.
This will be useful now because the username is the community username
