How do I research new technologies?
Research allows you to upgrade and improve the technologies your cities need to progress. In order to begin researching you need to construct an Academy. Once this is built, you can begin researching.
To begin researching an item, click on your Academy and choose the item you'd like to begin researching. A status update bar will appear in the lower right hand corner of your game screen displaying what you're researching and how much longer you will be researching the item.
You are able to research one technology at a time in each city you have. If you have an Academy in two cities, you will be able to research two technologies- one in each city. You do not need to re-research technologies in your additional cities, the research levels carry over. However, you will need to have an Academy and the appropriate level buildings to conduct further research.
