I'm interested. I have a few concepts that I'm really into right now and I'd love to flesh them out. I can also sprite somewhat decently, and I can write pretty well, if any of that helps.
Also, I hear where you're coming from with the "not completing any projects" thing as I have had a tendency to do that too in the past. I'd really like to have something with my name on it, that I helped create.
If you're interested, shoot me a message and I'll send you some of my ideas.
