How do I research different technologies?
To begin researching a new technology, click on your Science Center in the City view. In the window that appears click the button labeled "Research".
This will bring up a window displaying all available research choices. Next to the pictures of each technology is the name and description, followed by the requirements and a blue ‘Research’ button. Press this button to begin researching the selected technology.
If the requirements are not met, a dialogue will display informing you, and the unmet requirements will be highlighted in a red font.
