As long as one dont want to change/rearrange complicated stuff like grapics, techs and scripts, it should be a LOT easier.
I just want to start with a clean settler-free map - then point-and-click cities and terrain-improvements for each civ all over the map, from a palette.
Then i want to click these cities and add some city-improvments/wonders/units from another palette; city by city, regardless what civ it is.

I want to do this without ever to hit the next-turn Enter-button. The advances in the tech-tree should update it self for each civ, automatically. Finally i want to tie the whole thing up, by point-and-click the status for each civ, in terms of diplomacy, economy, happiness and government.
The scenario-editor then automatically calculates the estimated number of turns it normally should have take in order to achieve above.
