Of course there is night time in Divinity 2. What a silly idea that there isn't.
There just isn't a day-night cycle, so it all seems to take place on one day. But you can see night time at least twice: After you meet Talana, you pass out and Damian wakes you up at night, and later on, it's night in Broken Valley when Damian is razing it to the ground.
I'm a little confused by the equipment screen in one of the screenshots, it looks like there are two chest pieces, but no pants piece. Is one of those chest pieces actually shoulder pauldrons?
I went through all he screenshots - can't find it.
This one.
http://www.jeuxvideo.com/screenshots/images/00045/00045054_000.htmThere are a LOT of screenshots on that site, including some really neat concept art, and shots of the editor in action.
