"Everybody needs money. That's why they call it money."
The idea of monetizing RPG products is somewhat divisive. Huge Ruined Scott has always been adamant, as far as I can tell, that his creations will always be available for free. Kent also has strong views that RPG-related stuff should be created and shared for free, and people who try to sell them are grubby, greedy and vain.
I have some sympathy with that sort of stance. I used to have a button for PayPal donations which I never really felt comfortable with and eventually removed, because it didn't sit right with me to imply that I expected anybody ought to feel that I thought I deserved money for this constant stream of bullshit I spew forth onto the internet. The clumsiness of that sentence is strong evidence for the argument that I don't deserve it.
Moreover, I think there is something honourable and good about creating things for others to use, for nothing in return. It is something to be encouraged.
And nor do I need the money. I have a good job. When I finish and release Yoon-Suin, it's not as if it will make a material difference to my life even if I were to charge money for it. I'll spend it on booze and women and just waste the rest.
On the other hand, let's not kid ourselves: I like money. And being paid for doing something is a nice feeling. It shows that your work is valued. I have done enough freelancing to be aware of that - working hard to produce something and sending it off for financial reward gives you warm fuzzies simply by dint of showing that your work is worth something. It wouldn't be human not to enjoy that feeling.
I'm also of the view that people value things they pay for above what they get for free. I've downloaded plenty of free products (lawfully) that I have never so much as looked at, because since they are free I subconsciously view them as throwaway. If I've paid for something, though, you can be sure I'll give it due care and attention.
"I listen to money singing. It's like looking down
From long french windows at a provincial town
The slums, the canal, the churches ornate and mad
In the evening sun. It is intensely sad."
