Silverhawk170485: In the meantime I found it, but thanks. :)
It was funny. I saw the "bulldoze button" but I always thought that this button has the function to destruct the building, like it in many other games has. xD
Exactly it is sooo confusing XD
And for people a bit lost too, the "?" always gives a lot of indications on each menu.
And too in the "statistical" menu (the icon next to the "load/save" menu) where there is the
glossary which gives a lot of indication on populations.
I'm really enjoying this game, but I wish there was a better tutorial... and that there was the manual :P
Fortunately, ingame help is really helpful :)
