If only we led the horse to MORE water.So, it occurred to me you could do something more like Gumshoe, where you don't go through the describe-declare-check-results loop for searches, just give them clues.
Humans not being horses I tend to try and give them more of a benefit of the doubt. It doesn't always work out but I have rarely regretted it.This is leading the horse to MORE water.
In fairness to the PCs, looking for loot is a specific character desire. Some PCs want for nothing. Some might consider looting unlawful or selfish. Hobbits might consider it rude (unless their party claims the loot once belonged to them...)They wouldn't search for secret doors most of the time, and often wouldn't open obvious containers.
Skeletons are gross. Web-covered skeletons are disgusting! But an exception can be made if a long-lost key is needed.I started being more obvious and they would walk right past treasure. One time I said "You see a skeleton covered in the webbing, and you see something shiny on it." They didn't clear out the webs or search the skeleton or anything.
I don't expect high quality from ancient shields. Was the sarcophagus +1 as well?Another time I said "The room has a sarcophagus and a shield hanging on the wall." The did not look at the shield, which was a +1 shield.
An ancient tomb was probably already looted in ancient times. Or so thoroughly sealed as to make finding and delving into one a serious inconvenience.They also were horrible with clues. The plan was that some ancient kings always buried themselves at the site of their first victory in battle. They could figure that out, do some research on the kings and the battles, and find all the tombs. They never researched anything.
I don't know what to do about #2 above. I have never had to deal with that sort of player.
I think this is the heart of the problem: I just have a bunch of casual players. I think what I am going to do is treat them as other player types based on small deviations I've noticed from the casual player type. I'll let that ride for a while and then have an intermission session to make sure everyone is still enjoying the game.Its not really that uncommon for some sorts of really casual players. They'll either go through kind of on autopilot, or pay a bit more (but only a bit) attention to the parts they care about and mostly disregard the rest.
This brings up a situation I’ve had in some games where players think that the clues and everything should simply be handled with dice rolls and that they weren’t required to actually think through or solve the puzzle or clues themselves. They thought the clue solving was somehow handled by the system. I had one player try to roll to deduce what the clues meant and I told him that he could only roll for the clues but that he or the group would need to think through the meaning of those clues. It helped!
