Actully, it's so hard to estimate the amount of players. There are new players that enter the server 24/7 if you estimated how much people joined in a time ratio, you maybe could find a close estimate on how much new players enter a day and or even people who play in a day. You also can include that there are close to 30-80 players on each day and throughtout the day. People tend to share there find in a server if they like it. Also if you round that all up and estimate it, you have alot of players.
