For those of you who have played FFXIV, you'll know that there's a massive amount of dungeons. What this idea consists of is basically recreating some of these dungeons for play in Skyrim. Admittedly I realize this could be a gigantic pain, even if you have knowledge of what each dungeon is just by trying to find places for each one alone, let alone the mechanics that some of the bosses have(quite honestly I don't think I could complain if you decided to try it, just by switching up some of the mechanic heavy bosses for just incredibly powerful foes) However if anyone is willing to attempt to recreate a dungeon or raid from the game it would be much appreciated. I'll set a list here in spoilers so those interested can take a look and perhaps give one a shot. If anyone wants to know what a specific dungeon is, please reply or send a PM. If I were to describe all of them... it'd cover at least 3 pages. As a small idea should someone decide to try multiple of them, due to the placements of dungeons already it might not be too difficult to set up an NPC who gives options on what dungeons you can access and teleports you there when you select one. The teleport points for when you exit out of the entrance or the actual exit of the dungeon could take you back to the NPC in question. This could prevent conflicting areas. Of course I do admit I don't know how difficult this would actually be.
