Sim City 2 hides unlockable maps

Over at Game Watch, they have an interesting look at a neat feature in Sim City 2 for the DS. They're showing off several different types of the buildings available for you to plunk down in your virtual city, as one might imagine there being in a game where you erect cities, but what's interesting here is the unlockable maps.

Now, machine translation hasn't given us a 100% clear picture on how to unlock these maps (or how many there are, for that matter) and what is needed to essentially "clear" them, but we do know it's a password-based system that will unlock them and that, much like the scenarios in the Sim City of old, you'll start these bonus maps at a certain period in the city's development.

Click on through to check out some screens from the unlockable maps.
