First up, I am really enjoying the game and think you guys have done a great job with it.
The only issue I am finding is that as a casual gamer, I dont often have a great deal of time to play, but when I get the chance I like to know in advance what I am in for. So when I select a quest to go on I pay close attention to the "length" that is listed. This gives me a great idea as to how long I am expecting to be involved with a quest and unavailable to the world (it is so engrossing the house could burn to the ground around me and I wouldn't notice).
So the problem is, when play through some quests, you reach the end and suddenly discover there is an extention to which you basically have no choice to continue. Recalling at this point means you would have to do it all over again to get to the second part.
Would it be possible to actually state at the beginning of the quest that it is an extended quest and that you are in for more than just a single "long" period? At least that way I know in advance to only do them when I know I have time... There is nothing worse than telling those around you that you will only be 30 minutes only to get into a double "long" quest and taking over an hour.
