New and improved idea
After having discovered that my idea had already been thought up, I'm registering my new idea here so I can say I thought of it first :)
The concept: Bank Robbery! You've just pulled off a daring robbery and now have to escape the police. Lose them, and make it to the safehouse! Top-down GTA1/2 style gameplay, but without all the stealing of cars or splatting of pedestrians. You've committed enough felonies for one day :)
