Was at a work dinner, and this man asked me what my hobbies were. I said (among other things) that I'm a PC gamer, and he asked "how do you define gaming?".
I was a bit thrown by this, and now I find myself wondering, are there some rules about which games you must play to be allowed to call yourself a gamer that I don't know about? And if so, which games qualify, and what do you call people that play other games on their PC? What is a gamer?
