A fun project I came up with when I drew a mock up of what a Cube roguelike would look like in ACIIDraw.
For the uniformed, Cube is a Canadian movie. Watch it or just look at the wikipedia page
here.Build a giant cube. Can be underground or above, just make sure it takes up a lot of space, both sideways and upwards. Inside the cube, put multiple cube shaped rooms (All the same architecturally. They all have to be smooth.), and have all of them be connected by a door or hatch in four different directions horizontally and two vertically. Put traps (Fatal traps, no cages. Home made traps, such as dumping magma on the victim, can be used to spice it up.) in 50% of all the rooms, and make sure that in the trapped rooms every square is trapped. Put exactly one exit to the whole cube. Put any number of unlucky kobolds, goblins, elves and/or humans in cages, just make sure that they aren't your dwarfs, because that kinda defeats the purpose. Put these cages in the cube in random places. Open the cages. Watch as they either die horribly in the traps or kill each other. Edit: Set it up so that every route is the same number of steps to the edge. Thanks Tallefred.
Bonus: Make sure the cubes are consistent, such as making sure each cube as it's own color.
Bonus: Nickname the captives after prisons.
Massive Bonus: Let the one who actually manages to leave live.
Super Massive Bonus: Abandon the fort, get a bunch of companions and enter the Cube.
Easy Mode: Get rid of trap avoid on all sentient creatures.
If you find a more efficient way of dumping them in the Cube, just tell me.
I am just posting this here to see if it actually works, and if it does, then I will put it on the Dwarf wiki page.
