Several games have a promotion for, 'Recruit a Friend'.
I believe both of the Everquests as well as World of Warcraft.
Maybe others, not sure though.
From inside 'Account Management', you send an RAF invite to an email address.
That could even be your own email, for extra accounts.
The link/code in the email is used to create the accounts.
After which, they can be upgraded to full accounts via retail/digital cd-keys.
The two accounts (parent & referred) are then linked and get several benefits.
They level a lot faster, when they're grouped together if they're basically the same level.
When the referred account pays for game time (beyond the free month, for starting the game), the parent account gets a credit of some sort.
In wow, when the referred account pays for the 2nd month, the parent gains a special mount and when the referred account pays for a 3rd month the parent account is credited with one free month of play time.
