As I was reading , my first instinct was to yell Buy the Great Zimbabwe , but I see you already have . You have small groups that like small , but involved games . As to other mystery games , nab a copy of Mythos Tales before it ' s gone , and some Martian Chronicles web only they are a better Sherlock Holmes Consulting Detective than SHCD . You may or may not enjoy time stories , I ' m guessing it may feel a bit simpler than you hoped , but it does have a nice save game feature and 90 minite play times . For your leanings towards CDWG I ' m going to suggest Command and Color Ancients and Cuba Libre . CL has a short deck option which would fit your play time , and CC ancients is fast to play takes some time to sticker up before playing though . Happy Gaming !
