One of the earlier attempts at online multiplayer gaming with full screen graphics, TSN was a (pricy) BBS service which supplied various card games, chess, checkers and so on. Somewhat like the Wii today, you could create your own persona which is how others would see you online. This is marked version 10.2 so there must have been many revisions made before this point. Eventually more sophisticated games like Shadow of Yserbius were added as well. Services like TSN paved the way for modern online gaming. Once again Sierra bravely led the charge into new and unexplored territory.
