Codemasters racer FUEL may be the most open game ever created, according to producer Phil Wright. FUEL is arguably the most open-world game there is, Wright told VG247. Apart from the artificial boundaries at the edges of the game world, the only impediments to going where you want are natural, be that water, a sheer rock-face, or using the wrong type of vehicle (for example, trying to drive a road car up a steep slope off-road). It takes a few hours to drive from one edge of the landscape to another, but it can be done. The title, shipping at the end of May, features a meld of American environments, the collation of which was a labour of love for developer Asobo.
