No, I completely agree, and encourage people to customize the messages. The intent at least with my stuff was always to give people something they could tweak to suit their particular game, which would be a little easier than starting from scratch.
That said, I increasingly think that it’s necessary, accessibility-wise, to have an explicitly tutorial opening that teaches people the essential commands as they play. That’s what pretty much every other kind of game does these days. Walls of text are overwhelming and unattractive. I also think that if you ask people if they want to play on easy mode, or whether they want instructions, half the time they will say no even though they need those instructions. That’s why I’ve gone over to prefacing instructional content with “have you played interactive fiction before?”, a factual question I feel they’re less likely to lie about directly, and turn off the tutorial if they answer yes.
