Well, I'm involved with a project called the No Press RPG Anthology, which is a collection of several small indie RPGs in one book.
If I understand what Luke Crane, the guy organizing the project, is saying, artists will be getting $20 a piece for contributing. I know my contribution, Pretender, has three pieces of illustration I'd like to see.
If you're interested, check out the art direction thread regarding the project on the Forge, as well as the original threads.
To my understanding, the games in the anthology will include:
That's just to give you an idea of the sort of games we're talking about here.
I know that in particular I'm willing to pony up the money for the pieces I described for my game in the art direction thread. Regardless, if you're interested, you should probably post to that thread and let people know your skills are available.
