> In fact writing is never one person’s game. Otherwise why bother to write.
Ever hear of personal diaries or lecture notes? People write to formulate their thoughts, reflect on their lives, record something so they can remember it later, establish a base of ideas on which to build on top of, etc.
It could possibly be argued that at some point what they will interact with others, and they might use the results of those thoughts in the interaction, and therefore indirectly the writing is not single-player, but unless you're a hermit living in the mountains that's just something that has to happen and "single-player" becomes a bit useless as a definition. I might as well start saying single-player board and video games are multi-player then, too, as I might take skills I picked up playing them into the real world.
Like I've got about 300,000 words in a personal diary. Some of them I intend to maybe eventually turn into blog posts, but the vast majority of those words I will most likely keep private until my death (after that point, whatever). But every once in a while I reread some entries, and help remember some details about my life that I have since forgotten. Also there's a bunch of game designs I recorded that I might need to get a reminder of what I was thinking when I double back to them.
But those journals aren't going to build me an audience sitting on my hard drive or physically written on a notebook.
