I have a couple suggestions that might expand the game and keep its players while making it more fun.
First off: add more property and cities. currently there are a small amount of land and one man owns the vast majority of it.
Second: Im taking a couple of suggestions from other people but Add governments. They should be able to set interest rates, taxes, subsidies, and most importantly inflation. Inflation is needed for an expanding player base and giving the governments more money. Subsidies are needed for either struggling businesses or lowering prices. Taxes are needed to give the government more money.
How it should be elected. Elected council to make the decisions to prevent the monopolys making deions that only profit them. Need a new business for political campaigns to prevent to many candidates and fraud.
If The admin has motivatan issues for not being profitable add banner ads and make vip not free but it bans adds. just to make it more profitable
Im taking another suggestion from another person and its to add automation to. While it will lesson the amount of jobs it will add more use for other materials. Make it cost a certain amount of concrete, electricity, and money to automate a certain amount of jobs and each level automates more jobs. make it require a construction company to build it and for each level. Make it cost electricity and some money to run the automation.
Add more companies like maybe a mining one.
Add a progressively increasing tax on the wealthy and people holding a lot of property.
These are just some suggestions to make the game better and large. Because right now its incredibly difficult for beginners because of the closed economy and the monopolys owns there entire supply chain. and also one man controlling 70% of the property.
