You will be building several buildings and structures during your game play. A few are already in your game when you first start and do not need to be built. The rest will need to be built from 1 to 3 stages.
We STRONGLY recommend you follow the quest lines before you start building anything. Rewards for completing the quests will include materials for upgrading stages to your buildings. In the early stages of this game, it will be extremely difficult to replace some materials used. Be careful you don’t “jump ahead” and build extra buildings unless a quest tells you to do so.
