I'm trying Morrowind Rebirth. It isn't perfectly made (and kills my FPS) but new dungeons are surprisingly well made and balanced. So far I finished three - a secret cult in Seyda Neen, a tower-turned-dunmer necropolis between Caldera and Balmora, and sewers turning forgotten cave system turning dwemer ruins occupied by necromancer underneath Balmora (Thousand Lanterns Way).
Sadly there is no dialogue or journal entries about that content but dungeons are fun enough to go through even without them.
First mini dungeon is a tower locked by imperial legion in the outskirts of Seyda Neen. I had to kill some smugglers and buy opening scrolls because my character didn't have Security in her skills. Tower itself is standard but well made, with necromancer's lab at the top and an entrance to basement where you find magic circle. Using it teleports you through suspicious wall into a running underground corridor with some rooms, cultists and a prison where an imperial legion soldier (also a skill trainer) is held. Perhaps it's actually a part of some imperial legion quest but he had no dialogue sadly. Enemies are strong for new character but doable, and one wears full suit of iron armor. It's a simple dungeon but very nice. Somehow reminded me of M&M.
Oh and Mentor's Ring is now guarded by a lich. Had to return later prepared.
Second dungeon I found was a castle on previously empty island in vanilla, with skeletons around. Inside there was p. standard Bethesda plot-mess of rats and killed imperial bodies, darkness and a journal about all that. Inside a chest marked "evidence" I found some magical stuff and telvanni-kind robe. Things became hot when I went downwards where skeleton bodies started to rise up and attack. Not too easy when you play mage with 7 armor from Unarmored being your best defence at level 4. Jump scares with skeletons became old quickly, but then following through forgotten tomb I opened a door to main necropolis that had at least half a hundred skeletons, often attacking at the same time. The boss was a skeleton with unique silver sword and a shield with constant albeit small mana regen. Not unbalanced and useless in combat but unique for Morrowind. I also got a robe with constant +10 Alchemy on it.
Thousand Lantern's Way was the longest dungeon. I think I spent whole evening going through it. It is as long as some Skyrim's dungeons. Morrowind generally doesn't have anything like it. It begins in (new) sewers of Balmora and has two entrances which also both serve as exits - depending which one you pick. Both are hidden underwater but mod throws you some potions in other part of the sewers. You can either go through some cultists who are all summoners capable of using atronach spells and into dwemer ruin, or swim through forgotten cave, fight some smugglers and go another way. Enemies are tough either way, I found ranged enemies attacking me from places I couldn't reach, duos of mages summoning and using absorb spells, strong melee dudes, dark tunnels with some jump scares, cool new elevators (modder even left a note on how to use them and not fall to your death because of engine clipping issues) and a few bosses. I found two amulets with +10 Conjuration constant effect, ebony staff with absorb health on hit and some robes. Overall not bad but probably even too long.
Aside from various balancing which I am so far comfortable with (except summoned creatures not filling soulgems anymore... yeaah, fix that but leave shit like Fortify Skill untouched, like it's the most broken part), Rebirth tries to make world more believable. It expands on cities, adds imperial checkpoints and forts, farms, new buildings (like windmills), shops, traders, and small details like hidden caches of loot. However the FPS hit you suffer inside new cities (grabbed from mods like Epic Balmora I believe), and the fact that it doesn't expand on dialogue and quests like LGNPC does makes value of these additions questionable. It is also not compatible with grass mod from Overhaul, although high level of detail and new content makes up for it.
why would you delay that? Plus, just including that is such a spoiler. Besides, that assassisnation was awesome because you didn't see it coming. Why change something the developers intended?
