Yep, LEGO endures. I've done entire branded boxes filled with a custom instruction booklet, such as "build this diorama of our video game studio" or "this is a character from our upcoming game" or "it's a LEGO GameBoy with our game on the screen." And it has to be LEGO. Anything else is considered cheap and reflects on your company.

The top-tier of this, of course, is to have LEGO make a special set and color for you, like the Maersk promotion sets: https://brickipedia.fandom.com/wiki/Maersk

(Now it's kind of boring because they sell them online, before those were exceptionally rare as they were basically only sold directly to Maersk.)
