From the introduction:
[The Bionicle TRPG is] a fanmade tabletop role playing game for Bionicle. Interest in Bionicle is currently increasing with the possibility of its return, so this, I feel, is a good time for this project to start. Assuming a potential Bionicle revival does not completely deviate from the original, both the first and next generations of Bionicle should be incorporated into the TRPG.

Tabletop role playing games are interactive, multi-player games that require no special technology to play; only pencil, paper and dice (in theory). This restricts the complexity of the game, since players must perform all needed calculations and create all assets appearing in the game. However, it also allows players to be as creative as they like in their character creation and in-game choices.
