Our group spent the weekend holed up in a cabin playing AD&D 1E.
My players spent about 4 hours planning their entry into a small fort occupied by entrenched kobolds. After many hours of deliberation, they gave up and went back to base. 1E can be very unforgiving, and I their near death experience in their last game put the fear into them. They had at least one plan that would have gotten them in undetected, but ultimately decided that it wasn't worth the risk. Easiest session in the world to DM. I got to just sit back and listen to them deliberate.
While in Verbobonc, the party began to receive increasing reports of mischief done by one of the party members. During the investigation, the mischief spread to include additional party members. While following the trail from crime scene to crime scene, one of the party members caught sight of himself looking him in the face, giving him a wink and running off. The chase culminated in an alleyway ambush by dopplegangers. A critical hit by the fighter's doppleganger took him to within an inch of his life. The party very narrowly able make it out of the encounter alive, after the last monster (barely) standing failed his morale check, and was blown apart by magic missiles as he turned to flee.
I love my party. They're relative newbs, and every monster is new to them! Out of character, they're fab humans that I'm lucky to know.
How was your game?
