It is also the great-grandfather of much of video gaming. Why? D&D, the product of Gary's rich imagination was based on a key insight to merge character, narrative and stats into a 'game engine'. D&D envisioned a fictional world simulator designed to be played within (and with). This core idea is still the basic framework for so much of today's video games industry. For example D&D has Hit Points and Damage Modifiers, Hit Rolls and Armour Classes - how many other video games, even non-RPGs, have borrowed this combat framework? D&D has progression with character levels, equipment, skills, spells and more. How many games use the various incarnations of levelling up to keep players interested? Tens of thousands. D&D gave roles to the participants via character classes such as Fighter, Magic User, Cleric, Thief and more. How many games use this approach of allowing the player to map their identity into the game? The answer is legion.
