Expedition: general discussions.

Perhaps, it would be a good idea to create a sub-section for additional information (that which doesn't fit within the scope of a specific game or needs to be placed elsewhere) regarding the settings of the expeditions. Mixing it with game-related topics isn't the best idea, but the sub-section itself wouldn't interfere in any way (I don't pay attention to the "psychological mafia," for example), even if it isn't updated with new information.
I would move the deleted topic somewhere else, by the way.
