I think I may be down for this again, but only if the project is scaled back significantly. While what we had wasn't super ambitious, I think I'd like to aim for something more simple.
I really think just a small game with no real purpose with a level editor would be cool. You could even do the samurai thing, just have a level editor made up and stick with that. Skip the story and all. Nowone really cares if its a good game or not, just make it playable and fun enough to do. What matters is proving the community could come together on something.
