The definition of a toy nowadays is a lot more complicated and advanced than when I was still a kid. A small toy car, a plush bear, heck even a new eraser or pencil sharpener counted. Now, toys have to use batteries, be smart, connect to your phone in some form or another, and be expandable to suck you further in their franchise.
But as far as these kinds of toys go, Anki's Overdrive is kinda cool. It's a racing track with the obvious phone connection, where you can upgrade your cars and their capabilities, build the track as you want with the different elements, and even expand on it with more cars, track parts, and players. The kit includes 2 cars, 6 curved and 4 straight track pieces, 2 riser pieces, 1 charging system, and 1 tire cleaner.
The Anki Overdrive Starter Kit was released in the fall of 2015 for $150 and has dropped in price a couple of times to $120, but it's now down to $99.99 on Amazon. Right now, it sits as the number 1 sold remote control vehicle toy on Amazon with an average rating of 4.3 stars. Shipping is free and it should be with you before Christmas to give to the kids in your life, including yourself.
