EVE Online, like many MMOs, is best enjoyed with a friend, if for no other reason than to have at least one other person you can safely attack with minimal fear of retaliation. The development team has added a new incentive to people bringing their friends in to try the game with the addition of buddy invites to trial accounts. Try the game, invite your friend, and if they pay money for the game, you get a subscription for yourself.
Anyone who sends out a buddy invite that is used and converts to a full account will receive an account upgrade from a trial to a full account, with 30 days of subscription time. That also allows players on the former trial account to use PLEX and otherwise extend their subscription. For more details and information on corner cases like two buddy invites being redeemed, check out the full news post.
