I am very interested. And I think mostly because I want to see if I can convince you of my idea. I'm an advance level player as well, have been for a few years, and I really enjoy character interaction. 

I love complex stories and settings with sort of extreme circumstances. Lot's of tension and emotional anxiety. <- if that piqued your interest rather than stiffled it, I think we should do fine. 

I have an idea for a 22nd century exploration of a small segment of Mars. It wouldn't be for colonization or anything, but rather to excavate and plot a newly discovered, massive subterranean cavern. Essentially we would play space archaeologists in this sort of low tech sci-fi setting. Imagine, if you can, Indiana Jones meets Aliens :rolleyes

Let me know what you think. I also have other ideas.
