It's just relaxing to build Legos while watching a silly video to the side. I've built every set that's available besides the Marina Bay Sands (which seems to be broken/grayed out) and saved Tower Bridge as the "final boss". I don't think there were any issues with the build order for Tower Bridge.
I enjoy the diversity of experiences that building different types of larger and smaller sets brings (but larger than the Tower Bridge might have too many issues). The only ones I didn't really like were the tiny ~10 ish piece animals that barely look like anything.
Thank you for all of your work on this!
