Cheat Mode

I know it's still early days, but please please please please please can you guys put in a cheat mode, even if it is just unlimited $ or something?
One thing I really love to do once I've "finished" or played through a game like this, is it use cheats so that I can build/design whatever I want, and don't have to worry so much about the money side of things.
And as far as I can tell, the only downside to having a cheat mode is when you start having online interactions, or competitions, so if the saved game where a cheat is activated is easily and visibly flagged such, then it shouldn't be a problem right?
