dtgreene: With the release of Dungeon Hack here, I was just thinking about how the game offers a whole bunch of options with respect to dungeon generation. In other words, you aren't restricted to just the difficulty settings the game offers; you can, for instance, play an otherwise Easy game where food is scarce, or an otherwise Hard game that doesn't have water levels or permadeath.

I am wondering whether there are any turn-based roguelikes that have similar levels of difficulty customization.

dtgreene: What I am interested in isn't so much options for character development, but rather options that affect the dungeon. For example, make food more or less common, make water non-existant, disable level-draining enemies, make wands more common and arrows less common, that kind of thing. Also, I would prefer if things could be set individually, so I could play a game on a difficulty like hard, except that, for example, food is common or bosses are easy. (Also, of course, an option for how big the dungeon is.)
