Was George Orwell an Optimist?
Art Blakey and the Jazz Messengers - Mosaic
I'be just received this game in a trade and two of the ghost figures are missing. How bad will it affect the gameplay?
You could substitute salt and pepper shakers or anything else you dream up and it wouldn't affect game play whatsoever. Aesthetically it would be less than ideal; the question is how much that would bug you.
On the plus side it wouldn't come up that often - it's rare to have all the haunters in play simultaneously, and odds are you'll be dead in short order should that occur.
