There's a lot going on in the Arcade Mode in the new Project Gotham Racing 4. You can learn how to bike, race in a PVP mode, drift, and more in all kinds of weather conditions with all sorts of cars. It's pretty robust all the way through, and there are 108 medals that can be earned in this mode. Looks like it's going to be a lot of fun.
The entire thing takes place over several different chapters, each chapter designed to show off a different racing discipline. The game is imminent, to be released on North America on October 2nd. It's going to be pretty fierce when it comes.
