What players say
81% of 26,863 reviews are positive · 79% of 154 in the last 30 days
Players most often praise the crew management, adjustable simulation depth, and cascading emergencies created by damage and repairs. Since the Distant Coasts update, many players report frequent crashes, broken saves or base functions, failed crew tasks, and visual glitches; some say later hotfixes have not resolved the major issues.
