An RPG connects character growth to the player's actions. Experience, levels, skills, equipment, relationships, or completed quests can open new combat options and new ways to move through the story. The player may control one defined hero, create a custom character, or manage a party whose members have different abilities and goals.
Quests give that growth a purpose. A main quest advances the central conflict, while optional work can reveal another character, location, reward, or decision. Dialogue choices may change a relationship or later event. Exploration can uncover equipment, information, and encounters that make a different route possible. Not every RPG branches in the same way, but the genre normally tracks decisions and progression beyond a single match.
Combat covers several structures. Baldur's Gate 3 uses a party and turn-based encounters based on Dungeons & Dragons rules, including initiative, advantage, environmental interactions, and character abilities. An action RPG asks the player to aim, dodge, block, or attack in real time while still managing a build. An online RPG can place many players in the same world and organize progress around classes, group duties, story quests, equipment, and continuing updates.
Statistics are useful only when they affect play. Strength may improve a weapon attack, a dialogue skill may unlock a response, and equipment can trade speed for protection or change an ability. Some games show these calculations directly; others keep much of the math behind the interface. Fantasy, science fiction, horror, and historical settings can all support an RPG because the defining structure is sustained character development, not one specific world or combat camera.
