Looks AND Feels like the real thing!!!

I had no idea that this set was going to FEEL in the hands like a Game Boy! All the buttons, switches, and dials bring me back to my childhood--it's totally strange how smell and touch can bring back nostalgia more than just appearances. But the set is more than just nostalgia; it is super fun to build! The engineering is INSANE with bricks being attached and oriented in every direction with novel techniques. As I assembled it I glowed with excitement trying to figure out what I was building and couldn't stop smiling. I love even the interior details like the CMOS save battery inside the cartridges. ALL the printing on the bricks and not a single sticker.... But the best part is this isn't a set you just put on a shelf. It's one you can pick up and hold and use and show your friends and have them touch it. There are so few LEGO sets like this one. Grab it before it's gone. I might pick up more for future gifts.

My favorite build so far...

This was my first official Lego build and loved every second of it. Building the gameboy was fun at every click and seeing the GB come together was fantastic. I was very impressed with the final product. The look ,the feel , Lego nailed it with this one!

A lovely build, very worthy of it's inspiration

This was a very relaxing build, the finished Gameboy looks just like the original from decades ago. Love the unique way that tires were used to create the start and select buttons and am thankful that Lego used printed pieces with minimal decals for this build.

Perfect down to the last minute detail

I have never built a Lego set that was so perfect in replicating what it was trying to replicate until this set. Every detail makes me giddy with joy. Even the green on the interior to make a PCB board or the battery in the Zelda cart. It's all perfect. And for the price? Let's just say we need more sets with this level of quality and dedication put in while being at this price point.

Incredibly Fun Build. Authentic look and feel

This may be my favorite Lego set of all time.. not just for the nostalgia, but for the build experience. I haven't had this much fun building a set in ages. Everything comes together in a tight and accurately designed manner. I LOVE the screenprinted pieces and, I rarely say this, LOVE the fact that the only stickers included are for the cartridges.. which is absolutely authentic to the real thing. Kudos to the designers and to Nintendo for making this happen. An absolute love letter to Game Boy fans. I felt like it was Christmas morning in 1989 again.
