Sword World RPG (ソード・ワールドRPG, Sōdo Wārudo Āru Pī Jī) is a Japanese tabletop role-playing game[1] created by Group SNE.

10 million copies of the related books including rulebooks, novels and replays have been sold.

Each 2d6 dice roll is translated into a more wide range of random numbers by using a rating table.

However, the largest continent, Alecrast (where Rune Soldier takes place) is the main setting.

Forcelia is a typical fantasy world heavily influenced by games such as Dungeons & Dragons and RuneQuest.

Currently (after the release of Battle Master supplement), there are 21 classes: Sword World RPG uses only two 6-sided dice as with the previous editions.

The supplement "Arcane Relics" has also added several subraces to core classes like Snow Elves, Small-Winged Lildraken, Pico Tabbits and Alisha Grassrunners.

Replays are RPG session logs arranged for reading, similar in style to light novels.

The game features branching plot paths and multiple endings, as well as virtual dice rolls that partially determine the events, character parameters, and enemy encounters.
