This week, He-Man and the Masters of the Universe will be turning 40. It isn’t often that an IP gets to make it to 10 years, let alone 40, so for this occasion, the company behind MOTU (as it is affectionately called) wanted to do something special. They invited Game Rant for a rare tour of the Mattel Design Center in Southern California, an opportunity that younger versions of ourselves could only dream of.
