What’s the best thing to come out of role-playing games that isn’t a RPG? Modern videogames.
Sure, without tabletop RPGs, you would still have puzzle games, platformers, and first-person shooters, but games with roleplaying elements: characters that level up, gaining new abilities, going on adventures and having ongoing stories — those wouldn’t exist. Imagine no Fallout series. No Mass Effect. No Final Fantasy. No Pokemon.
Today, when someone talks of playing a RPG, they’re most likely talking about something on a computer or videogame console.
