Saw this at GAF and was hoping to get some reaction without a crapload of popcorn pics.

Basically, they're changing up weather effects to give tracks a different feel, but no actual day and night type stuff.

You won't see different times of day per city because this involves recreating all the textures again (one for day and one for night). Whilst this wasn't a problem for our dev team, it was a problem fitting all this data onto a single DVD. So we've worked around the problem by providing different lighting models per city. For example, Macau is always in the daytime, but if you play it during a storm everything looks darker and more foreboding. If you play during a blizzard then things are slightly tinged blue and everything seems more frozen. Of course, playing this track in sunshine will make everything appear bright and yellowy.
