History of Role-playing Games
Like all good histories, we begin with a famous genius who sets
the ball rolling. In this case, it is the incredible visionary,
H. G. Wells. For not only was Wells the grandfather of science
fiction, he was also the grandfather of war-games. Which makes
him, if you like, the great-grandfather of role-playing games.

from Dungeons & Dragons. The early games were clearly related to
wargames, but with a twist. There was an explorational
component, expressed as keyed maps fully known only to the GM.
This map-based approach to adventure was vital to how adventures
Single player RPGs are games that are played by no more than 1
person. Usually, single player role playing games allow less

rules that were defined by the game developer. Namely, it is
less likely there will be a gamemaster to monitor play and
create customized interactions for a single player.
Role Play, simply defined, is acting.
Acting, as a character that you either create or pick from a
spectrum of pre-created characters. In some settings you
determine vital characteristics of your character, in others, it
is predetermined. You set your mind into this character, and
play it out by improvising the characters' moves.
