In the 1970s and 1980s another type of tabletop game caught on: Dungeons & Dragons. Started by Gary Gygax and Dave Arneson, D&D began as a way for them to personalize the battles of their fantasy war games. Eventually, it grew to become a massively popular fantasy roleplaying game, where players could personalize their heroes and search for treasure, battle deadly creatures, explore new worlds, and just generally immerse themselves in vivid stories.
