In a megabyte-driven world, you'd think kids would be playing solely with mega-tech toys.But at the recent Toy Fair 2013 in New York City, buyers gathered like kids on a playground around the booths stocked with the classics - wooden play sets and ride-on toys, craft materials, table games and building sets.
"Retro-style toys for the under-tween crowd are on the upswing," says Adrienne Appell of the Toy Industry Association.
Here's a look at some of the new offerings and popular classics worth hanging onto after kids outgrow them.
Building sets are hotter than ever, according to consumer market research firm NPD Group. The category grew nearly 20 percent in 2012, the group said. Lego's booth at the fair included new entries in the Lego City and Lego Friends categories, the new Galaxy Squad space fantasy sets, and the DUPLO Read and Build sets, among others.
K'Nex representatives were writing orders for glow-in-the-dark rollercoasters, and construction sets based on Angry Birds, Pac-Man and Super Mario. The manufacturer's Robo Battlers allow kids to make smaller figures and stick them together to make a more elaborate creation.
And Tinkertoys are turning 100 this year, now rendered in durable high-density plastic. The colorful components include perennial favorites like rods, spools and washers, as well as new bendable pieces.
Some toymakers were touting franchises beloved by today's kids' parents: board games and figures based on Cabbage Patch Dolls, Teenage Mutant Ninja Turtles and Fraggle Rock. New York-based Yottoy had old-timey books like "Harry the Dog," "The Poky Little Puppy" and "Scuffy the Tugboat" paired with plush toys.
But when a kid outgrows them or loses interest, which toys are worth keeping?
Those with sentimental value, perhaps - books, dolls or train sets that parents dream might one day be passed on to grandchildren.
Then there are collectibles.
"I think the ones based on popular movies and shows might have value. Couple that with a brand-name toy and you've got a potential collectible," says Bene Raia of Boston, an antiques picker on PBS' "Market Warriors."
And pay attention even to what's in those fast-food bags.
"One of the biggest surprises in toy collecting is the Happy Meal giveaway," Raia says. Tie-ins to films offer an instant cross-collectible, that is, an item of value in more than one collectors' marketplace. Whole sets command more on the resale market.
Raia says many toys from the Baby Boom era are valuable now - Louis Marx toy trains, Madame Alexander Cissy dolls from the 1950s, Parachute Jump erector sets from the '40s - especially if they have the original boxes and accessories.
"Some people will buy two boxes of Lego, one to play with and one to keep," Raia says. "It might sound extreme, but for the 'Star Wars' series it might be a good idea."
