With CTY Editor, you can edit the City Plan (*.cty) files in your AoE (RoR) data (data2) folder. These files give you some control over WHERE the computer player places its buildings. Check the included Documentation before firing the program.
You can also find a tutorial on using this utility in the Siege Workshop.
There's a bug I'm surprised nobody's mentioned so far: 2x2 buildings (houses and towers) appear a half square down and left (or everything else is a half square up and right). As Devyn's article says, the coordinates refer to the center. This wouldsn't be a big problem if it wasn't for not being able to overlap buildings. Other than that though this utility would be very useful.

I'd correct it, along with the credits display, the wall dragging function and some other minor problems that are no real menace, but still bug me;
unfortunately, however, I lost the source code. Don't ask me how I did it, I have no clue. It wasn't a HDD malfunction. I just can't find it anymore.
And to start it all over from the very beginning, I don't have the motivation, to be honest :( I can be convinced though - but you'd need lots of energy for that.
