After months of rumors and speculation, Lego has fully unveiled its brick-built recreation of the Nintendo Game Boy. Slated for launch October 1, the Lego Game Boy is available to preorder now at the Lego Store; it's not marked as an exclusive, so preorders should open at major retailers soon, too. The 421-piece replica is almost exactly the same size as the handheld that quickly became a worldwide sensation when it hit store shelves in Japan and North America in 1989. The Lego Game Boy looks awesome, and it has multiple interactive features that are sure to make Nintendo fans nostalgic for that wonderful era of handheld gaming.Lego Game BoyPart of Lego's display model series geared toward adult builders and collectors, the Game Boy building kit was announced back in January, but we're getting our first official look at the highly anticipated release as part of Lego's San Diego Comic-Con reveals. The Game Boy is tied with the Super Mario Piranha Plant as the most affordable display model in the Lego Nintendo lineup. It will be the eighth Nintendo-themed kit designed for adults since the pair kicked off their partnership with a replica of the Nintendo Entertainment System.Lego Nintendo Display Models for AdultsLego Nintendo Entertainment SystemThe Lego Game Boy's interactive features such as loading carts and displaying scenes from actual games is reminiscent of the Lego NES. Released back in August 2020 to launch Lego's partnership with Nintendo, the 2,646-piece set included the console with a functional top loader, a Super Mario Bros. cartridge, a wired NES controller, and a CRT TV with a stand. There's a crank on the side of the TV that moves Mario through a side-scrolling level. Even five years later, the NES is arguably the coolest gaming-related Lego set.Unfortunately, the Lego NES was officially retired late last year, and it's sold out at almost every major retailer--except for Amazon. A couple months back we noticed Amazon restocked the discontinued set but for a higher price. Amazon is selling the Lego NES for $60 above the MSRP before it was retired. Even with the Lego NES now going for $330 (was $270), we wouldn't be surprised to see this sell out due to the Game Boy's looming arrival. These two sets would naturally look great displayed next to each other.Here's the full list of Lego Nintendo display models. The most recent addition to the lineup is the 1,972-piece Mario Kart set with a large buildable Mario and his famous red kart. It launched in May on the Lego Store for $170 and arrived at major retailers earlier this month.
