No, wait, that's not right, let's try that again. Here's what actually happened in our imaginary RPG campaign:
Ever since Harry's player left, the group has been down to just two players plus the GM. It's been there before, of course, but with the UNIT players away for good, there's no sign of it changing on the horizon. The GM is finding this a bit limiting, with the players often needing a bit of back-up to get things done. So, when they take a shine to a robot character he's just introduced, he decides to make the tin dog into a "Party NPC": a GM-controlled character that nonetheless travels with, and helps out the PCs on their adventures.
Yes, I'm arguing that K9 is actually an NPC. But the title of this little series is "Companions as PCs", and K9 is usually regarded as a companion, so what on Earth am I up to?
