Make certain actions time dependent

For example, instead of instantly getting these, create and show a timer, so it'd take some time till they are built/done.

- when you build an infrastructure
- when you travel
- etc.

In case of travelling, imagine that it'd take some time to get from point a to point b, the time would depend on more factors.
Ie. the distance of course, and the type of travel you use, this way you could make all the travel tpes relevant, at the moment nationally railway is the way to go, once you have them you don't need anything else, for international travel you use tickets, vehicles are absolutel useless at this point (I think, correct me if I'm wrong)
