I wonder whether it would be practical to have different levels of guidance in game, comparable to the different difficulty settings. For example, the most detailed help might be a "Go here" marker with the last piece of relevant text, the next level down would be relevant text only and finally the "you're on your own" setting.
The historical order of the dialogue record is not very helpful, especially if, like me, you tend to go from place to place like the ball in a pinball machine. It would be much more useful if quest-relevant conversations were tagged with the quest name and searchable in game. This would be a great help if you only play for short periods at a time and have a poor memory - I fall into both groups particularly when playing after a few drinks.
