Player limitation is a strange business, a smart player will often buck at authority or ask why he cannot pursue some course of action, when it seems the most logical option. Sometimes this is a good thing, and a good party of inventive characters can drive the story as much or more than the GM.
However one is left wondering what subtle or not so subtle shepherding you have found to be palatable? Obviously this is a matter of taste, and with the modern prevalance and popularity of graphical picture books like Dear Esther and Bioshock: Infinite where there is no choice, no consequence and no real interaction, there are obviously players who just want to be told a story rather than play a game. But for those of us who like interactivity, what limitations do not chafe too heavily?
For myself I have found weather to be very effective, the avalanche in the pass in Icewind Dale for instance, a seemingly insurmountable obstacle, at least for low level characters.
