Re: worlds largest dungeon
I dont have the dungeon so I can't run it but I would also be on board as a player, even with the restrictions above, or perhaps especially with the restrictions above.
Honestly those 'create food and drink' type spells always struck me as detracting from the game, especially since I don't think it really fits with the 'fantasy' genre for every 10th level cleric to basically be Jesus and the 20th level ones to be God... It also sets off some other interesting dichotomies: Which is more important to loot from the tribe of orcs and carry away with you; their gold and silver, or the portions of their food stores that the party can eat...? And when you've killed that Purple Worm, what's your highest priority: getting to a safe place to rest, or fleeting and salting that sucker for dinner for the next week? I think it would add something to the story if these sorts of things were serious questions.
Oh, and lest I forget: though this one is very dark: "Is it actually cannibalism for the human to eat the corpse of an orc?" They can interbreed, but then, so can lions and tigers...
