@dike_j: With each dungeon that I overhaul, I'm going to try to preserve what was unique or distinctive about it and build on that, elaborating on the vanilla dungeon to give it some character and history. Hopefully, when you explore an overhauled dungeon, you will say, "Hey, this dungeon is cooler than I remember it being". The objective is to make exploring vanilla dungeons more engaging, just as Unique Landscapes makes wandering around in the wilderness more engaging.
@Dark Hound: Well, the goal is to overhaul the vanilla dungeons, not add new ones (doesn't mean I won't add
any but it won't be the focus of the mod). There are going to be conflicts either way. Hopefully the overhauled dungeons will be different enough from each other to make exploring them interesting again for jaded players.

I've been doing some concepting and coming up with lore extensions to better tie the dungeons into Tamriel's history and to provide some quest-like features. I say 'quest-like' because most of these features will be discovered during the course of exploration, not initiated by a conversation with an NPC (though there may be some of that as well). Basically, while exploring the dungeons, you will occasionally glean insights into the motivations and character of the dungeon's inhabitants, a bit of its history, and its relation to other dungeons. There will be narrative connections between certain dungeons. Also, these narrative subtexts can be used to form the basis of dungeon evolution as the story of the dungeon and its inhabitants 'unfolds'.
I'd like some help with two aspects of this mod which only requires that people share their knowledge:
- lore related to any dungeon, or any of the factions inhabiting any of the dungeons (bandits, marauders, goblins, etc.). Links would be useful.
- a list of mods that make changes to vanilla dungeons so that I can either avoid them or make changes/patches where necessary. Again, links will make my job easier. These can be mods that incorporate dungeons into quests, or change leveled lists, etc. (I don't use any of the big overhauls, so I don't know exactly how they change creature spawns in dungeons.)
I'm still interested in people's input and suggestions and any advice that people may have about dealing with compatibility issues so chime in if you have an opinion.
Edit: What do people think about custom crates, barrels, etc., that can be picked up and moved around for physics puzzles and such?
