Nintendo Lego set

I bought this Lego set for a friend , I actually have no idea how well the Lego set looked after it was built. I do know that the price seemed fair for a Lego set. My friend is an avid Nintendo collector and requested this as a gift. I would buy this Lego set if my teen asked for this since she took loves Lego.

Wonderful

This is one of the best Lego sets I’ve ever put together and for the price. It was a very fun and affordable build. I keep it next to my old game boy and I found myself reaching over to turn it off because it looks so realistic. I highly recommend this Lego set to anyone who enjoys Nintendo or just Lego themselves.

One of the coolest Lego sets ive ever seen!

This is one of the coolest Lego sets I've ever purchased! It's worth the price! It's so cool that it has 2 changeable game cartridges that can go INTO the Gameboy. Its got a cool screen that changes depending the way you move it. And the buttons are even pressable! Its just SO COOL.

Return to your childhood!

Simple build process and the end result is quite stellar. I just wish it would have taken a bit longer to build, but at 400-and-something pieces, I knew it would undoubtedly be a fairly quick build. Either way, the end result will put a smile on your face.

Great for a date night project

Bought this for my partner for Valentine's and it was a hit. It’s a really cool build, especially with the retro Game Boy details. We’ve been working on it together and it’s been a blast. Definitely recommend it if you want something fun to do as a couple!

Great gifts for video game lovers

I think my favorite part about this set is that the buttons are movable and that the screen changes. Doing this build is super fun and definitely a throwback to when you used to play with a game boy the buttons click like their actual buttons and you change out the screen to be Mario, the regular Nintendo or whatever

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.

It’s good

Build was fun and uses unique building technics I hadn’t seen before. The details on the motherboard of the games and console was a welcomed touch. The buttons feel like buttons and D-pad works, as odd as that feels to say. Solid pick up for any old school Nintendo fan

Just like the real thing

They nailed it with this set. The nostalgic look and feel to this were above expectations. Everything from the dials, working buttons and controls to the on/off switch and all the printed pieces for volume, contrast etc. Definitely a fun build and look great on the shelf, would recommend to anyone who enjoys a little nostalgia.
