Just a couple of nitpicky things:

I wouldn't say that "Hunt the Wumpus" "hit the internet". As you mention, it was one of the first games written for a microprocessor. Its presence on the internet, decades later, is happenstance. They're not connected phenomena.

Also, "Hunt the Wumpus" isn't really a text adventure, either. A text adventure is something like "Zork" or "Adventure": a game with a plot, a game with treasure gathering, and rooms to explore, etc. "Hunt the Wumpus" doesn't have anything near the sophistication.

Nitpicking over. :)

Oh come on now.. The only thing it lacks is anything more than a serial plot. D&D often doesn't involve any treasures, it's pretty bleak like htw. You have rooms to explore, there are dangers, it is adventurous, and you type in text commands.
You want your kids telling you that Final Fantasy I isn't an RPG because it doesn't have digital voice-overs? :P
