Set in the modern era. Basically, the scenario is about a housing crisis, and you need to build houses for everyone, except every time you plop down a housing unit, there is a 30% chance that it will be stolen by a real estate company, who will jack up the rent so that the housing unit is one tier above where it should be, so for example, you build a tenement for poor people, the real estate company steals it and makes it a well-off housing without increasing the housing quality. You also can't destroy the stolen houses, but you can relocate them. There would also be scripted events where the stolen housing causes catastrophes due to cost-cutting measures from the real estate companies.

This is based on the housing crisis in like, Canada and other parts of the world where up to 31% of all housing is owned by chinese real estate companies
