Is there a mod that adds a huge 60+ floor dungeon to Morrowind. Like in the Tower of Druaga anime, with many different zones and habitats within? I was feeling like a dungeon romp recently and this would be perfect for an rp. Thanks for your time.

I'm not sure about large dungeons with different environments but there are some very big dungeons around including one that has 1000 levels. I can't find the links to the ones I know about but here are some links to anothr other very large dungeon mod.

This is a combination of several other large dungeon mods with new ones that connect various locations around Vvardenfell with realistic distances.

EDIT: The link in the above post has links to the mods I was thinking of.

I think there are one or two mods with dungeons of that size,
but they were done with a program that automates the construction process.

As such, they were rather bland, and well... mass-produced looking, as I recall.

You just can't beat good old fashioned hand craftsmanship, especially when it comes to modding.
They had to use such a program, though, because the project would have been far to daunting for one person, otherwise.
(So yes, there were several dugeon mods of such a size, but, to my knowledge, none that nice, or that could be called "atmospheric", as it were.

Sorry to disappoint you... But then again, maybe someone else knows of one I haven't seen.

Edit: Note that the ones I refer to just used the program, with little or no extra tweaking.
You could probably make a really great dungeon using it, if you then go back to tweak and finish it by hand.

I remembered playing an SNES game that had a special 99 level dungeon in it but it wasn't really that good either. The reason why I went to the bottom was because of the challenge of getting to the bottom of a 99 level dungeon.

Even Emma made a 100 level dungeon early on.

Ah, Twilight Princess has a very long dungeon called the "Cave of Ordeals" as I recall.
Interesting, AND challenging. It keeps getting harder, too.

It starts out rediculously easy, and gets tougher as you go deeper.
It eventually becomes harder than the final dungeon. (And it's completely optional, too.)

As I remember, you eventually have to fight a team of several Darknuts... at the same time!
Darknuts are nothing to sneeze at in this game... and a team of them is a killer.
(I do believe the fight could be harder than the final boss, for some people.)

Completely shameless self-promotion but http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=7768 is a genmod generated mod. I went through it with a fine toothed comb to make sure there were no errors. There's no story or quest or anything else, but if you feel like swinging an axe until your arms fall off, you'll love it. Bet you can't make it to the bottom without cheating!

Edit: I hadn't announced anything yet because I wanted to get more progress done, but I'm in the process of making a dungeon mod that is completely hand made. So far I have 9 super dungeons shelled out and plan on making at least 20 or 30 smaller dungeons. They will be spread all over Vvardenfell.

Thanks for all the replies everyone. I wasn't expecting answers so quickly, I will check out the auto generated dungeon mods. They sound like they could be what I am looking for, and to Kiteflyer61 I will be eagerly awaiting your mod, so I hope you make lots of progress ^_^ .

Also to Gaius Atrius I have had a copy of Twilight Princess laying around for a while so I am going to give that a try now too.
