On this site, “solo gaming” refers to a type of tabletop role-playing game (Wikipedia link) for just one person.
In more typical tabletop role-playing games, it’s common for one person to take the role of game master and the other participants to take the role of players.
In solo games, one person takes on both roles. Dice and tables of random options are often used for inspiration and direction.
While tabletop role-playing games are perhaps stereotyped as usually belonging to the genre of fantasy action-adventure, there are many different styles and approaches these days. This is true for solo gaming as well as the broader role-playing hobby.
Confusingly, the term “solo gaming” is sometimes used to refer to games with one game master and one player. These games for two people are also known (less confusingly) as “duet games”. I’m not planning to talk much about duet games on this site.
For me, solo gaming has become a source of very interesting and engrossing creative projects. In this category, I’ll be exploring resources for solo gaming and discussing my experiences. Currently, I haven’t played a wide range of solo games, and so it will be a while before I offer much advice of my own. I’ve completed one substantial solo gaming project, which is a historical fantasy story using the Fate system – I posted a write-up on the RPGnet forums at this link: The Border and Hedgerows.
