Tim Broadwater created a concept map for their research project on niche tabletop role-playing games (RPGs). The map shows core topics like the niche of tabletop RPGs, differences between European and American game design, and why sales of tabletop games are increasing. It also lists sources that discuss issues around identity, socialization, and creativity in tabletop RPGs or provide perspectives on game design and the gaming industry. The map will help Broadwater define their niche for a tabletop RPG, identify relevant skill sets, and consider time/cost viability when designing a niche tabletop RPG.
