Looking at the dev streams i’ve noticed you are doing some modular buildings. I think it’s pretty cool if in the tycoon part there will be some choices about the public display of the company.
For Example in recent years ('95+) an increasing slice of buyers is interested in enviromental awareness of a company, so, if you build a solar power plant on the roof of your factories they would be more willing to buy your car.
Some other ideas can be: a crash test course to increase the security feeling (like Volvo) or you can pump up the sells in a nation buiding your factories in that nation (you promise more jobs for people).
