Friendly Simmers here, having a chat, won't you join us?

Oddly enough, it seems EA knew what they were doing. The DD is being grabbed at roughly 25% per 15 minutes, so it'll just have given about everyone who's awake a chance to get it.

Of course, if there are sets on during the day, I imagine they'll be snapped up slightly faster. I wonder if they're going to have the time between longer in the overnight and shorter during the day (sorry people in Australia, I'm not biased, really. We're both jealous of people in Europe right now!)
