Forza Horizon 2's increased size and scope has been discussed by Playground Games.
The open-world driving game, which takes place in southern Europe, has three times more drivable space than its predecessor and over 100 hours of content.
"If there's a field or a vineyard in Tuscany which you can drive over in real life, we want you to be able to do that in our game," creative director Ralph Foulton told journalists including Digital Spy at E3 2014.
"What that means for us as designers, is we now have three times the space to fill with amazing things to do in cars.
"Not just races, but non-racing gameplay as well. Challenges, secrets, discoverables, things that encourage you to point your car in any given direction and drive to see what you find."
In addition to returning circuit and point-to-point races, Forza Horizon 2 introduces endurance races and new cross-country events.
Meanwhile, showcases are back and "bigger and more spectacular than ever"...
