As a student of logistics, supply chain and transport, I would like to suggest that you can make some explanations about materials or différents things, places, ships to learn more about this subject. It could be a great way to motivate news generations to take this way like a futur job.
For me, this game is a way to learn about logistics, shipping, inventory and many things. Maybe you can try to add news logistics and supply chain acteurs (like airport or urbain/rural logistics. 🙂
Best regards and thank you for your time.
