Boom & Bust cycle

The game should include the economic cycle. Recessions are an important part of any economy and government fiscal policy.

There is global economic cycle, but I guess at certain point its easily ignorable.

Yep. Most of the difficulty of the current UK scenario comes from where it happens to start in the (maybe somewhat excessively predictable) economic cycle. But then later on, once you’ve piled on a bunch of GDP-improving policies and GDP is capped at 1, you tend to be more or less impervious to changes in the global economy.
