A
role-playing video game (commonly referred to as
role-playing game or
RPG, and in the past was also known as
computer role-playing game or
CRPG) is a
video game genre where the player controls the actions of a main character (or several adventuring party members) immersed in some well-defined world. Many role-playing video games have origins in
pen-and-paper role-playing games (such as
Dungeons & Dragons) and use much of the same ,
settings and
game mechanics. Other major similarities with pen-and-paper games include developed story-telling and narrative elements, player character development, complexity, as well as
replayability and immersion. The electronic medium removes the necessity for a
gamemaster and increases combat resolution speed. RPGs have evolved from simple
text-based console-window games into visually rich
3D experiences.
