DCity is a terrific low maintenance city-building game. Unlike most other games that require frequent playing time in order to maintain your position, DCity allows you to make your investments, set and forget them.
From time to time, you do need to come back and make certain tweaks, like I have been doing in the last couple of days.
Renewed Education Focus
I have been buying universities to improve my education points and thereby increasing my chance to discover new technologies. Discovering these new technologies allows me to sell the excess cards and then re-invest them in more universities. Ideally, I want to reach the cap of 25%. This will require about 48 more universities.
Exporting Workers
The other area I'm working on is reducing the number of unemployed workers. By exporting them, I'm reducing my social support bill as well so it is sort of a win-win.
Of course, what would be even better is if I could attract more workers to export but the number has been stagnant for a while now. So the main income earner will be the duplicate technologies.
