Pretty sure this is in error, but if a destroyer sinks, the drone ships are fine since it specifies 'frigate' in the description. Also it amuses me that your answer to games taking up too much space is to require a 6' square.
You did do a very good job reducing the game to the bare essentials however.

I did not notice the frigate wording. My bad!
as for the space, I mean it in terms of dedicated space vs available space. for wargaming, you usually don't get on the floor, but this is perfect for the yard, and the 6' square is a suggestion. Mainly because everyone has a floor, but not everyone has a gaming table
