I was thinking it was weird that James rushed to get videos out so that his series would be ready for the new pack but hasn’t posted anything really since, especially as he had early access.
His output is actually quite baffling, especially as he's normally got these things planned out weeks in advance. He's been building up to the Infants pack for a month or so now, speeding through the last parts of his previous Lets' Play so he could have the family poised on the brink of a new generation, has been quite clearly looking forward to blending the branches of his Bigwallet family together...
...and then puts out 2 slightly sloppy and chaotic standalone videos about the basic infant update and the miniutae of the new likes/dislikes system. And nothing else. It's a funny sort of move when he's normally so meticulous about getting a build/buy overview and a Part One of a Lets' Play out ASAP.
I'm sure Deli would have informed everyone if something had come up, bless her, but there's no denying it's an odd blip on the part of James.
