This is basically Simutrans how it used to be before adding more and more features. Just a nice sandbox game with trains, trams, and cars--no airplanes, powerlines, or ships. And with a whole lot of beautiful graphics.
It does include economical elements but doesn't focus on them. This game is not so much about making money, it is about beautiful trains and building tracks. The economic part feels more like an afterthought to provide an artificial limit--it even can be turned off if you just want to build the railway system of your dreams.
The game would have profitted from a tutorial to introduce new players to the sometimes complicated mechanics. On the other hand, veterans of transport simulations in general and Simutrans in particular will have no difficulties, as everything works pretty much just as you would expect, including the menues.
Note however that you need a powerful (desktop) machine: Every single citizen, every vehicle, every detail of this world is simulated individually. All of the (depending on map size) potentially thousands of inhabitants have an individual home, and job. They go to work, return back home, and just go about their daily business. This potential "overkill" is certain to make your CPU sweat and get your fans howling, so a laptop might not be the best platfrom to run this on, especially later in the game when the cities start to grow.
