Adamastor - Solo playthrough - why this is a classic for every solo collection

About Adamastor, from BoardGameGeek:

As the captain of a fleet during the Age of Discovery, you have been chosen by your king to explore uncharted lands and map the edges of the known world. Each game presents a new challenge where you'll need to guide your crew with wisdom and resolve, all in service of your kingdom's glory. Fierce winds and sudden storms will test your leadership, while the cards in your hand will help you maintain morale and steer your crew across the seas. Though hardships may wear you down, they also teach you valuable skills to overcome the trials ahead. Victory lies in reaching your destination. But beware! Failure awaits if morale crumbles or your crew turns against you. Adamastor is a hand and tableau management game built around multi-use cards, with an optional story-driven campaign mode. Events trigger based on icon combinations, bringing harsh challenges-and occasional rewards. As you play, trauma cards accumulate, abstracting the crew's growing despair and escalating the difficulty. Whether in single sessions or the linked campaign, every voyage tests your resilience in this brutal age of sail. -description from the publisher
