High Quality Content by WIKIPEDIA articles! 2300 AD is a hard science fiction tabletop role-playing game created by Game Designers Workshop, originally offered as an alternative to the space opera portrayed by the company`s leading science fiction role-playing game, Traveller. In fact it was originally titled Traveller: 2300, but this caused confusion as the game used neither the rules system nor the setting of the original Traveller. The game was therefore renamed in its 2nd edition.
