What is rpg with a 20-sided die?

A RPG (role-playing game) that uses a 20-sided die is also known as a d20 system. It is a type of RPG where players use a 20-sided dice to determine the success or failure of their in-game actions.

The d20 system is commonly associated with the Dungeons & Dragons (D&D) RPG, which is one of the most popular RPGs in the world. In D&D, players create their own characters and embark on quests and adventures while rolling a 20-sided dice to determine the outcome of their actions.

The success or failure rate of a player's action depends on a number of factors including their character's ability scores, skills, and equipment. For instance, if a player's character has a high strength score and is attempting to lift a heavy object, they might have a higher chance of successfully completing the action by rolling a higher number on the d20.

Overall, the d20 system adds an element of chance and randomness to RPGs, making each playthrough unique and unpredictable. Players must also use strategy and critical thinking in order to succeed in their adventures and progress their characters.
