Let's see. I belonged to a Skype group that ran Call Of Cthulhu with the PCs being the characters from Scooby Doo (I was Scooby) that then played a Pandemonio game with the same premise. (I was Scooby again.) Then I later joined an open-world Unhallowed Metropolis game on Facebook. Then there was the Fallout tabletop I did one session of, and the 3.5 scenario where I played a stealth wizard. And then there's the technically ongoing (I say technically because real life has been consistently punching us in the face these past few weeks) Pathfinder game with a lot of the same people from the 3.5 game in it.
I confidently predict that I have been ninja'd in the time it took to type all of this. (Edit: ... huh.)
Have you ever pulled off a super-awesome assassination in a tabletop game?
