I'm not really sure, I was a supporter early on, but I gave up after 6 months of nothing but continuous excuses. BD either lies, or has the worst luck in the world (in which case I feel very sorry for him. but it was one after another of "I'm sick with a rare condition that limits me to 2 hours a day looking at a screen for the next 2 months while I heal, someone close to me died, I have the flu, I'm in depression because of the death, my computer is over heating, relationship issues, my computer's water cooling system sprang a leak, I'm sick again" always followed by, "But the update is coming along and only needs a little more work."
That being said, when he did finally release an update I noticed that the new house was totally changed, in that almost every surface had had texture or color alterations from the standard asset packs and was game specific, the most obvious is his room being decked out in WVM colors. So he did make tons of tiny little changes that add to the over all aesthetic, but his attention to detail is way greater than anything players typically notice or care much about. it does add for the immersive quality when you aren't constantly thinking, hey, that was also in this other game. but yeah, he takes it a bit into overkill.
