You're probably the only one who can answer that question, but here are a few thoughts anyway.
If you're interested in mechanic complexity and how machines work, Technic is indeed a good way to go. And as you hint, it can evolve into robotics, whether with a NXT or with anything else you fancy.
If you're after building complexity, I wouldn't recommend the ...
That part is the new Brick Separator which LEGO includes in most bigger sets:
It's not part of the construction itself, but is a tool to allow you to easily disassemble constructions. You can compare it with the older version in this question on how to separate 1x2 plates.
It seems like you understand why there are unique minifigs, but I'll point it out explicitly anyway. Unique minifigs add character to sets, and add to playability. For example, I always wanted this guy as a kid:
Without him, my pirates were just a leaderless band, but once they have a fearless leader with a peg leg and hook, things become a lot more ...
As far as regular sets go (ie. no furniture or big-boxes like that Chima combo), the current UCS Millennium Falcon does appear to be the largest box by total volume.
75192-1 Millennium Falcon - UCS (2nd edition)
54 x 45 x 39 cm = 94770 cm3
54 x 45 cm = 2430 cm2
The original UCS Millennium Falcon box was actually larger in 2 directions however, though the ...
I believe the main reason is so that the pieces are easy to identify in the instructions - as many LEGO sets don't have the Technic style "List of elements used in this step" it's always a fun game of "Spot the difference" to see what's changed:
If those pieces were all red, then the target audience (5+ on those sets for example) might find it very ...
As you've seen, the LEGO Friends sets are the latest theme aimed primarily at girls, however there are a number of current, and even more historical themes.
Other themes have included:
The Powerpuff Girls (2018 - ) - Uses Minifigs with custom heads, based on the popular Powerpuff Girls license
Elves (2015 - 2018) - Uses Minidolls similar to the Friends ...
Not a great pun, but the 2016 advent calendar was:
40222-1: Christmas Build-Up
Sort-of a pun/double-meaning on LEGO being a building toy, and the set being meant to build-up to Christmas.
The 2017 version also has the same name.
There are several discrepancies between the double-decker couch featured in The Sea Cow set and that depicted in the LEGO Movie. I've recreated the movie version as best I could in LDD and LDraw, and have compared it side-by-side with the Sea Cow set version. In the first picture, the Sea Cow set version is on the left, and the movie version is on the right, ...
3852-1: Sunblock (or Sun Block as styled on the packaging)
Here "Block" takes on 3 meaning, as part of the word "Sunblock", a pun on LEGO blocks (though I prefer to call them bricks), and a reference to the game play where you try to block your opponents from making another move.
You might be interested in the excellent, hilarious and comprehensive Communist LEGO report. It tells you all you can expect, from the good brands to the bad brands. At a minimum, it'll get you rolling of your chair with laughter.
A summary taken from the document:

Maybe straining the definition a little (although not too much, as at-least some of them did come with LEGO pieces), LEGO has in the past sold furniture.
I think all of these items were shipped disassembled, and I can't find much information on exactly how large the box they came in was and can't be sure what I did find is accurate, but I would imagine one ...
Some of the reasons (including some you've mentioned):
To make building easier / sturdier, so that the set is more suitable for its intended age range
The larger pieces are sometimes cheaper than the component pieces would be
The component parts may not be part of the current inventory of parts available to designers
To make the build interesting
To provide ...
As a conservative approach I would suggest the LEGO Juniors series which has cars and other sets and that are easy to build.
However, from first hand experience I can tell that kids learn quickly. Even if reading instructions is too difficult, playing with regular LEGO parts will soon be a lot of fun.
Besides : Losing small parts will be an issue with ...
You've already discovered yourself two good ways:
count by ten
put elements on large surface by type
The latter technique can be extended to an art called "knolling":
Place all elements by type in right lines with right angles on a large surface...
Its a very relaxing exercise and fun in its own right. Checking completeness becomes trivial, building ...
A brief search led me to a very thorough blog post by Ruth Suehle on GeekMom, which includes the data and a Graph:
Does It Feel Like Lego Bricks Just Keep Getting More Expensive?
In her findings, she found that average cost per piece in 2011 is about US$0.12, down from a high in the '80s of about US$0.40 - these prices were adjusted for inflation, etc.
LEGO bricks aren't suitable for children under 3 as they are considered a potential choking hazard.
LEGO also sell a DUPLO brand of construction toys which are twice the size of regular bricks. DUPLO bricks are designed for children aged 1½ to 5 years old.
I am not aware of any sellers that do this, but if you like to assemble discontinued sets, bricklink
has a feature that allows you to do this using bricklink seller inventories. Just look up the set on bricklink, add the Inventory to your wishlist and review which sellers have the pieces you need, then order them.
Go to the "Wanted" tab on Bricklink: http://...
The largest LEGO set by piece count is :
75192-1: Millennium Falcon (2017)
Piece count: 7541
Second: 71043-1: Hogwarts Castle (2018)
Piece count: 6020
Set 10189-1 - Taj Mahal (2008) (re-released as 10256-1 Taj Mahal (2016))
piece count : 5922
Largest Techic set :
42100-1: Liebherr R 9800 (2019)
Piece count : 4108
As well as the new colours (two new shades each of blue, purple and green), there are actually quite a few new parts in the friends sets. I think this is the complete list, but it's possible I missed one or two. (Let me know of any corrections. It's a big list!)
Friends Accessories Cupcake Holder
Friends Accessories Cutlery Fork
First, LEGO did at some point reissue some sets (the "legends" series), but then stopped doing so, and it's likely they found out it was not really that interesting to do.
The reasons why would be pure speculation, but at the very least building techniques and available parts do evolve in a way that older sets wouldn't be able to compete with recent ones. ...
Maybe this question would better fit the Science Fiction & Fantasy or MovieStack Exchange, as it's more about the tv-series you're looking for than about LEGO, which just reminds you of that symbol.
It absolutely looks like the Triforce of the video game series Zelda. There also was a Zelda cartoon in the late 1980s / early 1990s. To this point, ...
With the exception of evergreen themes like CITY and Duplo, it's not easy to predict when sets are released. Based on trends of the last 11 years, I've included the last 20 train sets that have been released in a table:
At least one train set has been released each year apart from the year 2008. The table marks an average of 1.66 train sets per year. It's ...
ALL parts can be used for something other than the original theme.
Here's an example of a use for the boat hull by Flickr user 2 Much Caffeine:
There's also a rather humorous saying that goes: "All parts are space parts". It's equally applicable to any other theme.
As part of this answer to the question: Does Toy 'R Us (or more expensive-than-average) retailers have more extra parts than average?, user Ambo100 posted a reply from LEGO Customer Services which also has relevance to this question.
When it comes to spare parts, it is random what pieces are included in
which sets. We always want to make sure our fans ...
It's an interesting question.
As Joubarc stated there are multiple approaches here. But from my personal experience I would recommend a graduated approach into the Lego Technic.
You should start with the sets on this page to see it you can find any kind of interest and to ensure you are not simply discouraged by the Lego Technic models.
If you enjoyed the ...
LEGO Group also did a range called LEGO Baby or Primo, which was pretty much suitable from birth.
It's not currently in production, but does come up on ebay and the like now and again, and is slightly inter-usable with Duplo and hence standard LEGO blocks.
Items ranged from things like this rattle, with chewable petals:
To the more "advanced" building ...
