Ha! I hope you've enjoyed Camp Grizzly. That game has been so much fun for us. The expansions are (theoretically) set to come out early next year. They'll definitely add to the replayability of the game.
As for Endure the Stars, the BGG Marketplace isn't the most intuitive process in the world. Shoot me a Geekmail, and I can explain how we operate in more detail.
I did enjoy Camp Grizzly and can't wait for the expansions. I'll send you a Geekmail about the BGG Marketplace. Unfortunately, I won't be making purchases until sometime next year, but I'd still like to know how the whole process works when going through BGG.
