I can see the last badge to earn is called "End of Phase I", does it mean a Phase II will come? If so, I hope phase II can be operated in "tech-tree" manner. Players in Kong love Tech-tree so much and games with Tech tree always rated highly. I gave an example how upgrades can be in form of "Tech-Tree":
First: Once Newspaper stands goes beyond 1500, upgrade the Newspaper Stand to
Choice A: "Crazy Newspaper Supermarket" !
Choice B: "Imperial News Domination Ltd"!
Choice A will provide extra benefits to other invest.
Upgrade 1: Profits of all invest x 3
Upgrade 2: Profits of all invest x 6
Upgrade 3: Profits of all invest x 9
Choice B provides extremely high profits boost on Newspaper alone:
Upgrade 1: Profits of Newspaper x 30
Upgrade 2: Profits of Newspaper x 150
Upgrade 3: Profits of Newspaper x 450
