The scores on the Metaverse are calculated as the total number of scores / the square root of number of games submitted.
I.e. 10,000 points played in 36 games would be 10,000 / 6.
The value of each game does decrease in value slightly each month in order to reward currently active players but the decay is fairly gradual.
