There's a fun thread over the on the OD&D74 forum that starts with Mike Mornard recounting a recent game of TRACTICS. In the second comment, Chirine relates this anecdote from the Twin Cities:
In the 'straight RPG' sense, observation is just as important. Follow me back in time to the days of yesteryear, when it was a dull evening at the old house and we were bored. We were sitting around, and musing on the very best marching order for a party of player-characters, and the idea came about that we should try an Actual Real-life Experiment. So, Gronan gets into his coat of plates, Olaf gets into his mail, and I hand Alfric (Gronan's squire) and Keith the Cleric a couple of lit candle lanterns. We then unlimber the rattan arsenal, we turn off all the lights in the house, and I - The Monster - go and hide someplace with my treasure of plastic gold pieces. The boys count to fifty, and then come in after me. They go Fighter (Gronan), Squire (Alfric), Cleric (Keith), and Fighter (Olaf); perfectly sound as a marching order, and all in accordance with what was considered Best Dungeon-crawling Practice.
It was awful. Me, I had lots of fun killing all of them in succession, several times over. (I had picked out several ambush points in the house.) A guy would appear out of the gloom, I'd give them a quick double tap on the back of the head to let them know they were dead, and they - being very sporting types! - would keel over dead to the horror and bafflement of the rest of the party. The next guy would look down to check the casualty, and I'd nail him. Then the cleric would try to see what he could do, and he'd get it. last and not least, the last guy in the line would try to see what was going on, and then he'd get it.
In the really dark corners of the house (Remember those attic stairs, Gronan? Oh, my...), I started at the back of the party and worked my way to the front. Same results. Two very experienced fighters, one pretty experienced squire, and one decent cleric all dead as the proverbial doornails saver times over.
What got them killed was lack of observation - not that they didn't try really hard, but that we learned that two fighters in *** closed face helms *** can't see much of anything. If the two unarmored guys weren't looking in the right place in the right time with the lantern held in just the right place, they couldn't see anything either. Most of the time, they said in the post-mortem, the light blinded them and ruined their night vision.
So, the RPG lessions for today:
1) Open-faced helms; a nice burgonet is a good idea.
2) Put the lanterns on a short chain on a short stick; you can keep it low, out of your eyes, and stick it into dark corners while keeping back out of striking range of some nasty lad like me.
3) Put a lightly armored fighter in the front as a scout; they can see better, move faster, and get out of the way of the heavies when they need to.
4) Do the same at the back, and have them keep looking to their rear.Success in RPGs, at least the way we used to play here in the northwoods, came from teamwork and communication back up by observation.
