July 9, 2008: Population Badge
The thresholds on the Population badge have been changed in order to make it easier to earn. The red badge is given for a world with 1,000 pop; orange - 2,000, yellow - 3,000, green - 4,000, blue - 5,000, violet - 7,500, silver - 10,000, gold - 15,000 population. Remember, that's for population on a single world, not total empire population.
This will take effect immediately in all pub and mega games.
