I would recommend to collect at first a few quests. Though it depends on how much time you have. Personally I would try to complete as many quests with as few gold as possible. Then moving on. At beta I've done 12-14 in the 1st town with little gold. Can't say for sure how much I've completed before I got stuck with lvl up managers.What's the thought on the first new city? Go as soon as you can, or collect a certain number of the tasks first?
