hey folks,
i'm portuguese so excuse my english. yesterday i was playing colonization. i decide activate the cheat menu and i discover something...
i create a colonist then i build a colony with this guy. i open the colony screen and prees simultaniously "shift" + "2" what i surprise!!! the town hall disappear, and if you press this buttons again the place were the town hall was is substiyuyed by trees and the town hall otion appears in the construction menu.
one question, when we can be able to change the ghrapics of the game. there are no image viewer in the net that can open this damned ss files???

i have a couple of scenarios for the game. in one of them england, france, holland and sweden stuggle for northeastern north america with the delawares, iroquois, hurons, abenakis, susquehannocks, mahicans...etc

the other is the american revolution: with quebec, montreal and the british forts in the interior in the hands of the british. new york ready to fallen in british hands...the iroquois and the western tribes in british side...

i want share scenarios with other people

thank's
