My wife and I may have acquired a LEGO addiction. I'm sure we've both had it since we were kids, but it started to take a serious turn when we scored a large haul of second hand LEGO from a local FB group.
That got us researching LEGO sets more seriously and discovering an active secondary market for LEGO sets. LEGO is continually bringing out new sets and retiring old sets. This creates rarity and means that some LEGO sets actually increase in value over time.
For example, an Ultimate Collectors Series Star Wars Millennium Falcon set which first sold for $500 now goes for over $3000 new on eBay and even used sets sell for a couple of grand.

The ability to view LEGO as an "investment" allowed my wife and I to justify spending more than we normally would on "toys", and being unable to decide on a set, I bought the Sydney Opera House set and my wife bought an Ewok Village.
The set arrived a few weeks ago: 
The set is rated as "expert", so I didn't want to start it until I knew I had enough time to devote to it. My wife got into action and planned a week holiday at a beach house with her family, a much needed break. So after few weeks wait while busy working my business, here I am at the end of day one of the holiday and I thought I would share my build experience on Steem.
The adventure begins...
The unboxing
My wife's Ewok Village
The Opera House
There were so many pieces, there is a box within the box:
I didn't count many bags there were, but there would have been at least 20. There are four volumes to the instruction booklet, so I will post my progress as it happens in four parts. Here are my pieces ready for part one, and my wife's pieces on the left:
Construction begins
Step one and it doesn't look much yet: 
Minor Mishap
By step 2 there was almost disaster. I couldn't find a piece. Had LEGO diddled me? What would I do? Use a different colour? But then I'd be short later! Crisis was averted when I found another bag of stage 1 pieces in with the bags for stage 2.
Hard at work
It was reasonably smooth sailing after that as the framework started taking shape and then steps were formed. There is a nice amount of detail in the steel girders and the blue water beneath and there are some interesting techniques used to achieve some of the shapes and angles.
After maybe an hour and a half, I had completed part 1 with only a few pieces "spare". We shall see if they are needed in the next stages.
Stay tuned as construction continues.
@brendio, since you mentioned Lego and how your wife is also a logo enthusiast, I wonder if you would care to tell me what you think of this:
Your thoughts might help me with something I am writing.
Many thanks, Oren
The video is a voice of common sense. Surprise, surprise, boys and girls generally like different toys. There will be exceptions for sure, but marketing campaigns shouldn't be driven by exceptions.
@berndio, thank you for your reply. May I ask how old are you?
I am late 30s, so I think that makes me Gen X. I am five months off becoming a father, so the whole parenting thing is still theoretical for me, but about to get very real.
Thanks for sharing this @brendio , as a father of 3 children, all I can tell you is, be prepared to an emotional roller coaster. My children are all grown up now so I can tell you that it never stops. Congratulations and good luck.
And if I may pick on you just a little bit more about Lego, you seem to be OK with different toys for boys and girls, but you also said that your wife is a Lego enthusiast too, so don't you think Lego might be missing something?
what a great collection of Lego. for some people, Lego are just some stones to play with, but I think it can even be a very good investment.
I have read an article that original Lego packages in good condition rise in Value more than gold and silver combined
amazing :)
