“Your character, Rene Belloq, ruthlessly opporunistic archaeologist, raging egotist, and sometime Nazi sympathizer, hijacks the cargo from his rival pothunter in the Well of Souls and discovers a large, gilded wooden box made from gold-plated acacia, ornately decorated with genuflecting angels on top. It is the Ark of the Covenant, and although it has been sealed for millennia and currently remains so, it indeed houses the original stone tablets bearing the Ten Commandments. Purportedly, it is a ‘radio for talking to God,’ but definitely don’t open it, or it will melt your face off…”
Got it.
No dramatic potential whatsoever in doing it the other way… 
I hear what you are saying. Immediate full disclosure of loot items keeps things moving and keeps everyone happy. I’m just not convinced it has to be the only way. That said, being the new guy taking the contrary point of view opposite immortals and moderators is a pretty uncomfortable place to be, even if my attempt at discussion is intended to be respectful, reasonable, and adequately outlined so as to have a chance to be considered valid. Better for me to listen, learn, and be enlightened.
Now is where I bow out and hope it’s not too late to follow some age-old advice: “Better to remain silent and be thought a fool than to speak [any further] and remove all doubt.”
