It might be motivating to see the top leaders for various stats.
I’d like it listed for different scales too, such as all time leader worldwide, monthly, weekly,
And by region, comparing countries, maybe cities.
Also have team competitions, and give the winning team a prize. And consolation prize for the losers. I favor having randomized teams to balance out the players. Not sure how to make it fair, but that’s for the game designers to figure out!
