I have been looking at the numerous mods involving new quests and dungeons. I'm particularly interested in the new dungeon mods because I am sure they have some dungeons that are far different from the somewhat similar-dungeons in the game (so I've heard; I'm new to the game). My question is whether these mods can be played after I've finished the game? Or are they only good for certain level characters? If they only work for certain character levels, then I assume I should add the quests into my game as I'm leveling up rather than waiting until I am too powerful for them to be any good. Thoughts?
All the mods I know that deal with dungeon crawling are designed with level 15 to level 25 characters in mind.
Some examples that I can recommend to you:
