IGN: PGR 4: Through Rain, Sleet, or Snow

"June 14, 2007 - Bizarre Creations has always been under pressure with the previous three Project Gotham Racing titles. PGR 1 was an Xbox launch title, PGR 2 helped launch Xbox Live, and PGR 3 was a 360 launch title. For the first time, Bizarre has been given a little breathing room and the freedom to create the next PGR without being attached to a major console or feature launch. Free of launch concerns, Bizarre is tricking out PGR 4 with a dynamic weather system.

Racers will now experience ten different weather variations, which can change during the race. And, more importantly, adverse weather will change the race itself. But, as Bizarre Creations' Community & Web Lead Ben Ward assured us, none of these elements are going to turn PGR from an arcade racer into a sim.

IGN and its sister site TeamXbox spoke with Ward at length to get the full run down on the new dynamic weather system."
