Yes, I believe a Text Adventure requires a much better story, plot, and puzzles to solve than do most or all other games, since there's nothing else to hide that element. First Person Shooters have amazing graphics and special effects, and some times fear involved to keep you interested, while it may have no story whatsoever. An RPG revolves around character development, usually with a party, and a lot of "leveling up" or improvement of your character throughout the game so that you can finally defeat whatever "boss" there is in some final battle. I'm not denying that RPG's don't have good stories / plots, but they have other things to keep you interested, like leveling up and seeing all the things you can do that you couldn't before now that you gained a level.
A text adventure on the other hand, doesn't have any of that. So to keep you involved, it has to be a really engaging story, and the interest lies in finding out what you can do now that the door that was locked the entire game has now been opened. There's no fighting to keep you interested or to keep you from leaving. There's no internal clock that keeps things running at all times so an Imp could pop out at any second and start scratching you. You could concievably leave whenever you wanted to. So there always has to be some major and really enjoyable quest that you're on so that you don't just leave whenever you want to. You want to see what happens after you put the talisman back in place. And you feel intelligent for figuring out the puzzle, not just lucky that you skirted death by a few hitpoints because a random number generator rolled in your favor.
Perhaps the reason I don't like MMORPGs is because there's no driving story to keep you compelled to find out what happens next. You can define your own story, which some people like, I guess, but I like a tailor-made plot-driven story, which is usually much more interesting than a generic world that has to be much more general to encompass anything you want to do, sacrificing story, plot twists, and specific "you-character" development throughout the main story of the game.
