Strange yet common to have such a weird pseudo religious gimmick to indoctrinate new employees with a symbol that doesn't serve the purpose it purports to. It's like Amazon's door desks, a symbol of frugality that costs more than a regular desk because they insist on custom building imitation doors instead of regular (and ergonomic) desks.
Why doesn't the one-time museum visit serve the purpose? Are Nintendo employees disbelieving that the company is serious about that balance between legacy and future?
