I've never actually played D&D (as this isn't really a "thing" where I live) but always really wanted to!
I've actually been doing some "historical" gaming posts lately, covering noteworthy games released in certain years (just made one about 1998) and it's fun to see how tons of games are inspired by D&D.
The D&D influence is quite vast even if some people don't realize it. We don't have games liek Skrim without first having D&D.
