For long time, in our group whenever the players set "we take time to search the room and search the bodies" I gave the all the information.
Now we are going to play a published adventure (The Unliving Light) and the adventure sometimes says that the information should be revealed "when the players move a body" or "on a successful DC15 Perception check".
I wonder if this is important. what can I do to switch to this style of exploration? or is this a minor enough source of the fun of a published adventure that I should not bother changing the way we approach searching rooms?
