I think CEsar's action/adventure mode idea is excellent, that way everyone gets what they want,,
well, maybe not the programmers, but that's another story

I think giving the player more freedom (or a sense of freedom) is always good, for me the option you had in Monkey Island was quite revolutionary at the time, choosing the mode of amount/difficulty of puzzles,,
I think TSL did an excellent job after people complained about overly long narrations, and having a short version is an excellent compromise. It gave the gameplay a jolt and made it a lot faster and more fun (for some people!),
cause it just shows that everyone's idea of fun and drive is relative and individual, and I think that's the way to go if you wanna create a solid, fun game.
and I actually think you could do the same for other parts of the game too, speeding up the gameplay (which in imo is by far the game's biggest problem, it's just too darn slow),
and there's a lot you can do, like an optional hint system, (doesn't have to be complex, maybe something like the universal hint system where you can click at different levels and get clues that are more and more revealing, gradually,,
and the option for a transportation map system that would extend the normal sea map to every screen (like in the kq3 fan game),
I think a lot of players would start out with the regular map, exploring the entire land by foot and then, the second time around check the option for a more in depth screen to screen transportation map system instead.
At least for me, that would have made the difference between waiting for the walkthrough or playing it,, right now!

but my point is, it doesn't have to be part of the game per se, like with the narrations, but an addon, bonus thingie you can choose from the main menu,, that way the purists have their way and the more impatient, action hungry people can have theirs,
and more freedom, more fun,, always
