Some quests may not be available for pick-up, until you meet certain requirements for the quest. Such Prerequisites can come in different shapes: a few of Coobico’s dungeons for example will not be accessible by merely walking there; they can only be reached by accepting a respective treasure-hunting quest, which in turn requires you to have some kind of ancient treasure-map.

As for city-building (which is also a quest, remember), a few prerequisites exist as well, namely the brickyard (to the right) and the blacksmith (to the left). The brickyard will enable building any structure besides the initial city-hall. Later on, before you can upgrade a village’s buildings to their second level, a blacksmith is needed.
We tossed in these two structures to avoid having to keep some kind of “tech-level” for settlements and tying this game-mechanism into our already existing quest-system. Coobico puts its focus more on personal actions rather than micro-management.
