The angle of that teaser clip was strawberry floating terrifying but that looks brilliant. It's basically the quintessential ingredients of a Mario bros level in a Lego playset with larger than life (as in mini fig scale).
And yeah it'll be a lot of micro controllers and NFC chips interacting, those OLEDs will make it expensive...
The problem with Mario toys as I see it has been, because the video game experience is so much more better and more interactive than a toy they have always seemed a bit pants because these things aren't talking and interacting together like they do in a game, and they're addressing that to make a better more innovative product. Lego and Nintendo are a perfect partnership for this, plus it ads the building element which games like Super Mario Maker have only very recently incorporated.
Squarely aimed at kids and in keeping with the Nintendo and Lego "play first" ideals, I dont think its for me but I might pick it up just cos its Mario and Lego. Hopefully this follows a similar path to the Minecraft stuff where the intial releases were testers and the bigger better sets followed after.
I wish the LEGO Mario stuff would have been something more. It'd have been amazing to have a Peach's Castle. If it had proved successful, they could have even gone onto do LEGO Mario Kart sets. Can't complain, though. It's being set up more like a toy than regular licenced LEGO series.
Also, looking at these 2020 Star Wars sets, I wish I could get back to collecting.
