I appreciate Captain Sonar, but I never want to play it anymore. You need exactly 8 people (10 player is not an option; the First Officer post is a dull busy work station) on board with knowing the game. Even one new or bad player sinks their whole team. You don’t want to get mad at them, but good lord how frustrating is it when you’re stuck with a clueless sonar player (or whoever keeps track of enemy movement)?
