I think it would make stuff a lot easier if they had a in game quest list so you can make sure if you did all of the quest in the world or on a street. If you think this is a good idea reply back and list your ideas
Half the fun is exploring. There is a point at which this game would simply be you watching your character play, or at least it would seem that way. I'm guessing you don't like Zeke's finding quests?
I agree and have menitoned this several different times on various boards.
I can see the need NOT to list quests if the main quest line of a world is still in progress.
But if the main quest line is completed, then somewhere the minor sides quests should be available for review. I know I have missed some and have not a clue where they are. Maps are not a help, revisting old areas multiple times does not seem to help.
If you've gone to everyone in a world and still didn't get a new quest, then you may have to wait until you complete other quests on other worlds, or are certain levels. Check back every so often.
