I recently met a programmer looking for a project, and posed to him the idea of a traditional western RPG. (Think Baldur's Gate, Arcanum, Fallout, etc. Project Eternity, for a current example.)
I'm a freelance writer, and I'm currently negotiating a novel deal with a couple of national publishing houses. I'm also an advanced-stage Lyme's Disease patient, leaving me almost completely disabled.
I've written a baseline script for said RPG, and after reviewing some ideas, we decided to give it a shot. He's been working on various mechanics and techniques in preparation for doing a game project, and I've been making notes within this fictional world and using it to DM table top RPGs for nearly ten years. Therefore, the conceptual and baseline content needs were filled rather quickly. I pulled in my personal assistant (from my novel's editorial team) and my artistically inclined wife to help with pixel art if we go that route. Thing us, none of us are experienced in that field, and while we could gradually produce acceptable art assets, it would dramatically lengthen the dev cycle.
I've written up the events (along with outlines for all elements and events of each scene) of a pretty solid demo of the game. We have grid-based combat with line-of-sight around objects, combat and exploration mechanics for an animated sprite-based interface. The UI is still a work in progress, it'll depend on some gameplay decisions as we flesh out a few unique mechanics.
Save for some basic script demos with empty placeholder sprites, there really isn't much to "show".
The story isn't something we're trying to put much info on the open web about--it's going to be a main draw to the game, once we formally announce the project (preferably after we've finalized a solid art direction, whether we produce it or not).
The point is, this project will be a proverbial first-entry in any sort of game development portfolio. That said, we'd rather push it back and produce our own art than get into a position where we'd spending the whole project trying to hold on to a team member who feels like they're doing everyone a big favor by showing up. We're all putting in time, and we've already put in quite a bit. All we're doing is putting it out there to see if anyone else is interested. If not, fine.
There are people who are actually interested in doing these things because they love to do it. That's the sort of team we have, and that's the sort of person we'd be interested in adding. Simple as that.
I could as easily treat the artist as if they need to prove they're worth representing my dozens of hours of writing, or the programmer could decide he'll only script for pro artists and writers, noobs not allowed. But then ... well, we'd just be a team of assholes. :)
