I believe in "free" RPG's. I have written several. Five by Five is one of those. I spend a lot of time looking for free RPGs to read. I also spend my fair share (my girlfriend would say *more* than my fair share) of money on non-free RPG's to try to support the industry and because ... I love RPG's. I love to read them. I love to play them. I think about them, write about them, and pretty much obsess over them most of the time.
If you are looking for free RPG's there are many places that you can go.
John Kim's Free RPGs on the Web is here: www.darkshire.net/jhkim/rpg/freerpgs/
Keeton Harrington's 1KM1KT (1 Thousand Monkeys, 1 Thousand Typewriters) is here: http://www.1km1kt.net

Chris' (Eric Garrison's) Compendium of Free Role Playing Games (aka www.homebrew.net/games/) is now here: http://ericgarrison.wordpress.com/about/games/
The Year of Living Free http://livingfree.wikidot.com/list-of-libre-games focuses on free RPGs that carry the Creative Commons License.
Commercial RPG Site RPGNow has a lot of free RPG goodness on offer. http://www.rpgnow.com/index.php?filters=0_2140_0_0_0&pfrom=0&pto=0
I am placing these sites in the links bar at the top of my blog (under the title.) Use them. Visit them often. There is a lot of real gems hidden away among those links.
I believe in Free RPG's. But, I also believe in the dream that creators foster of one day earning a living wage from the fruits of their creations. With a niche market that inspires so much creative output from its consumer base, the chance of earning any kind of commercial gain by writing an RPG seems especially remote.
A person who produces their game for free can only hope that someone out there reads it. Or joy of joy's, that someone out there actually plays it. I want to do my part, by putting the word out. Click on a few of the links above. Read through a few of the games that are listed. What have you got to lose? Certainly, not your money!
Edit: I removed the "Free RPG Day" graphic and replaced with the "In Philanthropy We Trust" badge from Rob Lang's Free RPG Blog. Rob's a huge supporter of the free RPG movement. Thanks, Rob!
