This set was so much fun to put together. The kids loved the activity together and it looks fantastic on display. This is actually inspired me to look into more LEGO sets that I can do with the kids. Even if you didn't have an original Game Boy (I didn't), this is a wonderful set and a ton of fun.

All the right nostalgia in all the right places

What a fantastic set! There are so many great qualities about it. The feel of the pushable buttons. The attention to detail. The (for the most part) printed bricks. It was a quick build, but I loved every moment of it, seeing how everything came together. My absolute favorite feature is the power switch! The way they made it feel like the real thing makes me smile every time. The nearly 1:1 scale is appreciated as well. Love love love this set to pieces (pun intended). I hope to see more consoles in the future!

Gameboy Lego fills any need for nostalgia[80s 90s]

I preordered this for my 10yo. He put it together and then showed it to everyone he saw throughout the night[to mean we had to take it with us in the truck]. He was very proud of it. He also said that ut was really fun to put together. In my opinion i feel that it nails giving me that feeling of nostalgia . Its also a really neat lego to have in any collection.

Best Christmas gift

Amazing Lego set. Gifted this to my adult son for Christmas and he loved it. It was his first Lego set ever and he is hooked. Now I know what to continue to get him as gifts. What started as a funny gift to get him a toy for Christmas turned out to be the best gift and a new hobby.

Quick, clever, and no visible studs.

Very easy and fast assembly, and looks absolutely flawless when finished. Instructions are clear and some of the building techniques are a little clever. The big plus for me is there are no visible studs! This is the only Lego set I've bought in a decade because I HATE visible studs and also because I primarily build military model sets (from Cobi, Sluban, and Quanguan), which Lego doesn't do. If Lego comes out with more retro stuff like this that doesn't have visible studs I'll buy them for sure.

Takes me back to my childhood

This Lego set is one of those that transports you back in time. The completed build is exactly what I remember from the original Gameboy™️ from the size and buttons, down to the stickers on the cartridges. I’m extremely impressed at how similar this replica set looks like the real thing! Very easy build- took about an hour to fully assemble. Definitely a great purchase for any Nintendo/Gameboy enthusiast!

What a great set

It's a fairly straightforward build but still cool to see how it all comes together. Loved the attention to detail and little nostalgia moments. The buttons being tactile, especially the power button, and the cartridges being able to click in made for a lovely surprise.

Unique and Fun build

I purchased this as a gift for my brother. The price was very affordable, especially for a lego set of this size. My brother absolutely loved it as we have both been big Nintendo fans since we were little. He loves that you can change out the display screen. This is a great set for any Nintendo lover.

Wonderful Build!

I usually do not write reviews and I mostly purchase Star Wars sets, but this set just called to me. I did not have a Gameboy as a kid but played with a friends. Building this was just so much fun. The building techniques used made the build just fly by. The way that the buttons, power on slider, and anything else that moved on the real product move on this set showed the extra effort Lego put into this product. Lego is not always great with design decisions but this one was spot on.

The look and feel of gaming nostalgia

Having the original Gameboy back in the day, this set brings back not only the look, but the feel of the distant memories. There are clever little mechanics to give the tactile feeling of the squishy buttons, soft d-pad movement, and even clicks of on/off. It shakes the memories of those older gaming days. The display stands and interchangeable game screens and cartridges bring the fun. And it is so close to the original, you can easily psych someone out that you are playing the old school Gameboy. Love the building of internal components and there even is a little save battery detail in Zelda cart. Take a trip back with this very tactile little gem!
