Here’s a question for discussion, what sort of “challenge” should we be going for?
The first one (I don’t like) is the metagame until you can find a teleporter and leave, basically having a character with eight extra points after a few tries.
The second I prefer the most, is staying at a depth of 1 or more, for the entire game. Maybe you can find an unlimited source of water, and with cannibal, use alarms and stuff to keep summoning zombies, or just have to keep rampaging through walls and depths if you want to survive. Ant farms, sewer, triffid stuff, etc is permitted, basically.
The third, hardest, would be only lab, all the time. Like even if we had to “enforce” the method by making the map generator only make labs across the entire world, possibly including the “sky” z-level, if we can’t make it a no-access zone.
