Domestic investment before imperial expansion

While upgrading Scotland, the campaign choice becomes a brief interpretation of British expansion. Britain had to invest in territory close to home because it lacked nearby uncontrolled land. That investment allowed technology and experience to accumulate before the state sought gains farther afield. Empire Total War compresses the process into a set of development choices, so this remains a strategic interpretation rather than a complete history of British imperial growth. Domestic capacity becomes the basis for later overseas expansion.
