In order to grow the playerbase of Earth, already existing players must invite a new player. This process takes around 9 months as of now.

The new player's character appearance and traits are inherited from parent players (it can be changed later during gameplay).

Sometimes, players may end up inviting more than one player at the same time. This may affect the gameplay both for parents and new players alike in unique ways.

In order to be able to invite new players to Earth, you must meet those requirements. If some requirements aren't met, attempting to invite new players may result in punishment from server's staff.

• Player must have an account age of 18 years or more
• In order to invite new players, you need another player. Depending on player's physical traits and potential debuffs, invitation may not be possible. Some servers offer alternative invitation methods, and in certain cases, you will not have to pay for it.
• For best results in early main scenario: Parent players must have a certain amount of money, a housing place and financial stability - for the first 18 years you are responsible for your invitee's actions and are required to provide for the new players.

Inviting new players on certain servers can bring various benefits, such as additional money, discounts at various merchants, priority in some services.

In some cases players might want to cancel their invitations.

While this is possible, most servers as of now make it a punishable action, and players might be restricted for terminating their invitation.

If your server allows terminating invitations, it can be done at plenty of Hospital locations by a Doctor class player.
