Well it's not really up to us at this point, game's done. Haha.
But, I think the weather is pre-determined by the level your in. And you play through the seasons in the SP.
It hasn't been said whether there is or is not dynamic weather, but I doubt it.
Yeah, that's true. I'm hoping there might be a little dynamic weather, like rain or high winds, nothing too crazy like UC3s dust storm.
