Why don't Star Traders ever launch more than one torp at a time in combat? Why can't they torp and gun at the same time?
Why doesn't anyone make jokes about how Steel Song Clanners listen to heavy metal music? Too easy a pun?
ST RPG combat is a sequence of single actions, imagine them as concurrent if you wish, but the game has a design that is action-turn and that's just the way it is designed, for the benefit of the player.
If multiple hyperwarp munitions detonate in the same space, their fields cancel each other out -- so that's why you don't see a barrage of torpedoes.
When we greet someone, we send a torpedo. When we run out of arguments, we send a torpedo. When someone asks us why, we send a torpedo. When we find a fly in our tea in Steel Song teapots, we launch a torpedo on the fly, then we go destroy some steel song ships.
Torps are awesome, which makes us feel awesome. And to ensure that it doesn't go to the hands of enemies, we have trademarked the torp awesomeness.
