Ricochets are fun. You get to roll lots of dice, and any one of them could potentially cause serious injury to an unsuspecting PC!
Players might attempt to take advantage of ricochets by aiming shots carefully to bounce off objects and hit targets they couldn't otherwise reach from their firing position. You should definitely let them try this!
Don't mention that the odds of them accidentally hitting themselves may be higher than hitting their intended target.
GM: You land in a sealed metal chamber—
Han: I blast the door open! 8!
GM: The shot ricochets wildly.
Luke: Great, we're trapped.
Leia: Put that thing away! You're going to get us all killed.
Han: Look, I had everything under control... And I still do!
Chewbacca: <sigh> I guess nothing much could be worse than this predicament.
Chewbacca: Just out of morbid curiosity, Han, what was your plan number six?
Han: Put us all in handcuffs and lock ourselves in a cell!
Chewbacca: Alas. Too late for that now.
