I was flabbergasted when I learned that for many, many people who play ttrpgs, that hobby essentially means D&D. Seemed like very few had played, or actually even heard, about other systems.
Which seems insane to me, considering how many other systems there are.

Play D&D if you like it, that's absolutely okay. I'm certainly not knocking it. I just personally don't really care for it. To me, it kind of is like picking the vanilla flavour, when there are so many other different options to choose from.

Also, a little side note regarding how ttrpgs are more acceptable now, and more mainstream. While I'm happy to have more people in the hobby, there is one downside: we old timers lost all street cred the hobby gave to us.  
When people saw us carrying a bunch of roleplaying books in the streets, they feared us! Parents ushered their kids to other side of the street, scared that I will use my demonic witch powers to convert little Timmy-Sally to a goth who plays vampire the masquerade.
That is respect. Well, that's fear, to be precise. But fear is better. Respect can vanish quickly, but most people can't stop fearing easily. 🤘
