After reading through the nightmare thread (And trying to suppress memories of my own bad moments) I figured we could use something to counterbalance the horror being generated by that thread. After all this hobby is supposed to be a source of entertainment and friendship, and it's kind of discouraging if the newbies come in and see a thread about all the terrible things people remember from partaking in it.
I'll start with a one-shot I ran in Saga a couple years back. This took place on Denon during the Clone Wars and featured the player characters attempting to stay alive during the CIS invasion of the planet while also trying to escape. They all met up with each other halfway through the session and eventually formed a plan to slice into the Separatist controller that was directing landing craft from the fleet to the local starport so that they could use the ships to cover their own escape. The climactic encounter of the session saw a Clone Scout, a Wookiee Soldier, and a Jedi Padawan fight their way to the top of the occupied control tower while the Noble and Scoundrel snuck aboard one of the transports they intended to use as their escape vehicle. The clone was badly wounded in the final fight by one of the Magnaguards defending the control room and a grenade had damaged the controller, so he volunteered to stay behind and reprogram it to let the others escape. The Wookiee and Jedi fled the tower by riding an amped-up repulsorchair out the window, since the turbolift was on its way up with reinforcements. By the time the lift got to the top they were aboard their ship and blasting off amidst the swarm of sacrificial droid transports, and the doors opened to reveal two droidekas and a commando droid.
Me: "The droids step forward, covering you with their blasters. The commando droid orders you to throw down your weapons if you want to live."
Clone: "I take my helmet off, toss away my blaster...and pull the last grenade from my belt."
I didn't even make him roll.
