I've seen it listed as The Chase Begins, but then, I'm not sure if it's a minor regional difference in titling between say, North America and Europe. It'll be interesting to see how this turns out, anyway, as the 3DS's first full open world sandbox game set in a city like this. Hopefully we'll get a trailer soon.
