Bridge Over Troubled Water

I was searching for the root path and I found it, it's the map. I started thinking with the brains of the average player who, in order to play, must perform some very precise steps. Select a scenario and load it for first. And this simple action unveils lots of issues, the first one being: how scenarios are being done? well I have to program a scenario builder. And what is the basis of this scenario builder? a map. How do you provide the map? many more questions rattle in my head. But the path is clear and this is more than enough for now.
