Lich Van Winkle's recent article is, as they all are, worth a read:
The Commodification of Fantasy Adventure Games
The final paragraph inspired a few thoughts in me.
I'm a creator who is also a consumer. I buy a fair bit of RPG stuff. I use less than I buy, but I do use some of what I get.
I derive a great deal of pleasure from playing games. I also derive a great deal of pleasure from creating for games. I largely sell what I use in my games. Or stuff I'd like to use in my games, on occasion. I've been briefly interviewed on a podcast, had my stuff reviewed, and otherwise gotten some recognition. I've had the great joy of dragging my spouse to a gaming store and pointing out my book on the shelf. I've gotten amusement out of people looking me up on the internet and finding my list of written books. It's even more fun when they know me only as a fighter, or a trainer, or a teacher. I also get a lot of enjoyment out of other people using stuff I made for my game in their games. I've even had the dubious amusement of having people argue with me about the intent behind rules that I wrote and tell me I'm wrong about my interpretation of the intent behind the rules.
None of this would happen if I hadn't been playing games with other people's stuff and with my own. You can see how a slowdown in play due to summer scheduling issues has slowed down my writing here. The play is the thing, and without the play, the supporting material just doesn't flow as freely. I still write - and I'm still creating for game. Playing more will mean more of that.
Oh, and it's terrifically fun, by the way, to quote rulebooks at my players when I wrote that part of the rulebook.
