If you receive the Lego catalogs, it's pretty evident that they're targeting all demographics now. The ultimate collector line of sets is aimed pretty squarely at the "investment" market and people with more money than sense. They recently started putting out sets for the nostalgia and pop culture markets with sets for the Flintstones, Steam Boat Willie, Stranger Things, and Friends.
You know when you're actively selling a toy set for a late 90s sitcom popular among 40 something single women that you're pandering to everyone. Honestly I'm surprised there isn't a Gilmore Girls set yet.
My four year old has the Summer, Fall, Late Holiday, and Christmas catalogs splayed out on the counter with all the sets she wants circled. Not surprisingly the following sets aren't on her shopping list:
4784 piece Imperial Star Destroyer
4108 piece Liebherr R 9800 Excavator
3306 piece 1989 Batmobile
2287 piece The Updside Down
1197 piece Trafalgar Square
1023 piece Harley-Davidson Fat Boy
826 piece Vestas Wind Turbine
I am a little offended she doesn't have the new Slave 1 set on her list though.
He'd still be doing it, too, if he'd not run out of room to build :P
("Age 16+" LEGOs really just require ... typical age 6-7 spatial skills plus not screaming in terror when you see thousands of pieces).
I definitely wanted to buy some sets to build, but they were out of production, and had outrageous prices.
I even had a spreadsheet trying to find nice sets with good pieces per dollar ratio, but the out of production sets had consistently poor one.
The Ghostbusters headquarters for example is a really nice set. In my national eBay shop, there are zero used sets available - only new ones. This is a clear example where collectors are depriving actual users of opportunity.
