Rockstar themselves have been talking about this game "creating a new market". How many games that create a new market sell out on their first week? Did Brain Training? Maybe you can call that marketing spin, but it's obviously their intent. This thread has already shown there isn't a market for M-rated games on DS yet, it has to be created.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
