I picked number two, but...
I selected number two on the poll, but it depends on how you judge "created your own RPG".
I currently have a single (my first) adventure module published: Kaidan - The Gift: Part 1 (available at the RPGNow Store) with two follow up modules on the way to completion.
Basically, I am creating a setting for Pathfinder RPG, but it has some very different rules regarding PC Death, Reincarnation, Spiritual Magic, Multi-classing, Social Caste Restrictions, its own Monsters, different versions of monsters in the Pathfinder Bestiary, a unique Undead mechanic, some new spells, feats, and unarmed combat techniques, a couple of new base classes and prestige classes - which, when I make its Core Rulebook, will be calling it Kaidan RPG. (scheduled for release sometime in early 2010)
But is it really a new RPG? Its definitely a different flavor of Pathfinder, with its own augmented crunch, but not sure whether that qualifies as a "new RPG" I can't say for sure.
I've spent about $725 in commissioned illustrations and cover designs, but that is covering three different modules and a fourth or fifth of the upcoming Kaidan splat book, including cover design (which is complete). So, I'm taking the venture seriously and neck deep in it already. Luckily for me, my products will include bunches of maps, since I am a pro RPG cartographer - which means, where most publishers can only afford a map or two, my adventures feature 10 or more maps per adventure; this makes my products especially unique.
Also to save me a little money, I have some skill in illustration myself (remember I do all the maps.) So something like 1 in 10 illustrations are mine for specific art, that I don't have to pay someone else to do.
Since I have so many "hats to wear": designer, editor, concept writer, primary writer/associative writer, proof-reader, art director, primary project cartographer, and chief marketer (plus website designer) - I can't put in as much of my art, as I don't have time to do that, which is the primary reason I commissioned the art. But I'm still glad I spent the money on commissions, the art so far, is great!
