Ok, hmmm does it matter how long u take to play this game ( a time limit? )? well i seem to be on chapter 3 already when i have not completed quests from chapter 1 or 2.I take i can still complete these quests? ( then go back to the story line? ) All i have done is explored 4 sections of the city and done the quest to de arnise Hold!

Unless specifically stated when you get the quest, there is generally no time limit to quests.
