I've got a bit of a story to tell that those who've played Nethack before might get a kick out of.
I've been playing the game since before it was ever called Nethack, since the late 80's (the version I tend to favor is 3.2.2). I've never beaten it before on my own merits outside of explore mode, as something or other keeps foiling me in-game and out. Technically I managed it once, but that was through continuous backing up and re-copying of my save file, so I don't really count that.
This past week, I was on a bit of a roll. I'd begun to think: "Hey, I may actually beat the game this time!" I'd managed to scour all but the bottom-most level and reach the Wizard of Yendor's tower in order to obtain the last of the items I'd need to access the Amulet. I freeze part of the moat, dig my way through the tower, and immediately get confronted by the Wizard. He summons monsters to fight me, so I go to waste them. Should be simple, right?
Well, not really. One of his monsters was a fire-breather, and it melted the ice I was standing on and made me drown. Could've been dealt with, except for one thing: I forgot to equip an amulet of magical breathing I had in my inventory.
Face.
Palm.
