The overall rule, which rules them all: We are here to have fun and enjoy ourselves, any and all rules are secondary.
When a rules question arises the GM/DM will make a decision and research the answer for the next game session, where a clarification will be made.
-Anything the DM has to ponder the full impact of for more than a minute is forbidden (or a VERY bad idea).
-A full minute of stunned silence means “My God what did you do?” not “Please continue.”
-I cannot have any gun mentioned in the Geneva Convention by name . . . without a good reason.
