@RecycleBin No joke. I was tunneling underground for real-time days just looking for ore when I broke through into a cavern miles underground that was the size of a continent.

After exploring it a while, I discovered that it was just a shelf opening up into a chasm going down forever. Then I stepped on a patch of gravel that gave out under me and plunged me into the abyss to my death.

In my desperation to recover the ore and equipment, I died four more times trying to tunnel-and-ladder my way to find the bottom of the pit. Finally hitting the bottom and recovering my previous incarnation's corpse (and gear) made for a memorable adventure. Especially since I discovered that "bottom" was just another shelf, and the abyss went down even further.
