Hi Julia,
For the past two to three years I've conducted an email conversation with Daniel Clark of FFG (he co-designed Lurker at the Threshold and worked on other expansions). He is the best I've found (especially in terms of patience) with answering AH rules questions. I'd like to share his answers with the Forum, but I don't know how to do anything with emails but send them to another email address. Do you have an email address I could send them to that would facilitate this?
Also, I'm now past the 350-game mark in AH ( I have all expansions), and continue to enjoy it. The only problem I have with it is that it is so much easier to win with a larger number of investigators than with a smaller number. I have found this to be consistently true, even though I never use more than one expansion board with three players and no more than two with four players. I think I recall you once mentioning that Eldritch Horror is designed to be better for fewer players. If you and others think it accomplishes that, I may be ready to try it.
Thanks for your help!
