Yup, we actually had it all documented in a little booklet called "Sniff & Listen", lol. We'd just hand it to the DM and tell him "unless we say otherwise, when we say 'Sniff & Listen' we're following this procedure, broken down by common situations, etc." A few DMs would try to balk, but we'd just get out the book and start down the list mercilessly the first few times, and pretty soon they got the idea. As our various parties leveled and got stuff, they would add their own modifications and addenda to the little book. IN GAME we had a "Delver's Society" and the book became its bible of SOP (it existed in a couple DM's worlds, admittedly kinda meta-game, but why not?).
Finally our one main DM started doing things like creating an entire dungeon out of Neutronium (perfectly immune to all magical and non-magical effects). Then when we sorted out how to get around all the hacks THAT prevented, he made a dungeon called CITY of the Beholders, which had literally limitless numbers of them in it. THAT we couldn't beat outright, although we did manage to loot a whole bunch of it (partly because we figured out how to steal some of the Neutronium and build a battle wagon out of it). He was/is a devious DM, but it is darn hard to totally thwart players that have really learned to exploit that kind of system.
After a while we went on to other games, lol.
