Back when we first played D&D, we rolled for secret doors, but not for ‘concealed doors’ (i.e.: a door behind a tapestry that you could not see unless you pulled aside the tapestry). Things that were concealed the player had to find by describing where they looked. This was (as far as we knew), the ‘correct’ way of doing it. There were no ‘search’ or ‘perception’ skills. And, if I ran a game again, I think this is how I would like to handle it.
I recall describing the characters using poles or weapons to probe things that were suspected of being trapped, etc., rather than using a dice roll. So if you thought the floor was trapped, you might toss the corpse of a dead opponent on it, etc. Personally, I find this style of play (where the player describes what or how they do things and results are adjudicated from that) to be a more immersive one than using a funny accent while speaking in the first person, predetermining psychological quirks that will artificially govern your character’s actions, etc., simply because you weren’t playing a part — you were attempting to insert yourself, mentally, into the role of the adventurer. So if you were actually physically searching the laboratory of an evil wizard for a hidden treasure, where would you start looking? I suppose one could both speak with an accent and adjudicate searches verbally, but I would posit that using accents and assuming mannerisms often falls under the general rubric of ‘roleplaying,’ as in, “I am playing the role of Fflunfreddles the Fighter who is stupid, superstitious and speaks with a broad Moronican accent…” I would offer that another interpretation of ‘roleplaying‘ might be, “I am placing myself in the role of Fflunfreddles the Fighter. I have these items and these skills. The referee has described the situation. Using what I have available in the game, what would I like to do?”
The person I was having the discussion with thought that the method I described took too much time (as opposed to using a search skill or similar mechanic). I don’t honestly think it takes up more time to adjudicate such minor tasks verbally rather than rolling for it (assuming ‘rolling for it’ involves the referee determining some sort of target number, the player (or DM) rolling a dice and adding modifiers, then comparing what is rolled to the target number, etc.).
I did notice that when I did it this way a few years ago, I did not tend to have a lot of rooms or encounter areas crowded with lots-and-lots of furnishings simply because it could get tedious to have the players describe exactly how they were searching in the 900 nooks and crannies one might find in a room crowded with furnishings… and, honestly, as DM I made up a lot of the inconsequential details on the fly. So maybe ‘realism’ in terms of room furnishings takes a hit, but so what? As DM I was not above ‘fast-forwarding’ through searches or activities that were routine (i.e.: if the player found a store room with 100 crates and announced they would search each one for valuables, I would have just determined how many hours it took, rolled for wandering monsters and given them the run-down on the contents).
