NCsoft has launched a new program designed to entice more players into subscribing to Tabula Rasa, the relatively new sci-fi RPG from Richard Garriot. With World of Warcraft, Lord Of The Rings Online and Everquest 2 holding a big chunk of the online market between them, they’ve laid out a fairly generous offer. Existing subscribers can send their friends a free three day trial of the game. If any of their friends like it enough that they themselves subscribe, the player who referred them gets a free month of the game tacked onto their subscription.
