Are there any games about becoming a space ship captain and commanding your crew on voyages of discovery?
The only one that comes to mind is Spelljammer, but I actually want to give orders to lieutenants and helmsmen.
Prospector is the game you're looking for. No other space roguelike surpassed this gem, for me at least. Crew management, ship management, stuff management, combined with planet exploration and constant feeling of discovery and wonder, goddamn. Brings so much memories.
Even did a LP here in Playground ages ago. It's lost due to my inability to pick a proper image hoster. Still have a few random screenshots saved, tho:
