Hello.

I've recently felt an intense craving to play Morrowind.
After some searching, I was quickly overwhelmed by the number of graphics overhaul mods for Morrowind and decided that figuring it all out will take more effort than it was worth. Plus I find default Morrowind to be quite outdated despite its charm.

So I decided to try to find an equivalent mod for Oblivion. Turn out there is a mod that lets you play Morrowind in all its glory in Oblivion - Morroblivion.
Here's the link to its official site: https://tesrenewal.com/morroblivion-faq

Installing Morroblivion took temporarily installing Morrowind, but it could be deleted after Morroblivion was installed.

By now my load order in Nexus Mod Manager (NMM) looked like this:
Oblivion.esm=1
Morrowind_ob.esm=1
Morrowind_ob.esp=1
Morrowind_ob - UCWUS.esp=1
Morrowind_ob - Chargen and Transport Mod.esp=1
Morrowind_ob - MorroblivionTreeReplacer.esp=1
Morrowind_ob - Morroblivion Maps.esp=1
Morrowind_ob - Conversation.esp=1
DLCBattlehornCastle.esp=1
DLCFrostcrag.esp=1
DLCMehrunesRazor.esp=1
DLCThievesDen.esp=1
DLCOrrery.esp=1
DLCSpellTomes.esp=1
DLCVileLair.esp=1
Knights.esp=1
DLCHorseArmor.esp=1
DLCShiveringIsles.esp=1

Just about any awesome mod for Oblivion needs OBSE, so I installed it next.

To figure out how to make Galaxy launch OBSE instead of Oblivion, check out these links.

I had no issues with the game, so it was time for the next step.

I'm a big fan of werewolves and I always found the customizing options of Skyrim's mods fantastic.
With the right mods, I could play as a relatively peaceful werewolf and NPCs ignore the fact that my character could become a furry kill machine, plus I didn't lose my gear and I could transform whenever I wanted for how long I wanted.

To my knowledge, Morrowind or Morroblivion don't have such mods.
Currently, I don't even know if Morroblivion has a werewolf system or not.
I'd prefer not to confuse the game with other mods until I know more.

Otherwise the best werewolf mods I've found on Oblivion's Nexus were:
- Curse of Hircine - Resurrected
Link: https://www.nexusmods.com/oblivion/mods/35118
- its addon Symphony of Night
Link: https://www.nexusmods.com/oblivion/mods/34924
- Wolven Anthros
Link: https://www.nexusmods.com/oblivion/mods/32821

Wolven Anthros is just a race mod so I deemed it safe to use without provoking crashes or bugs.
I don't mind if the "wolf feet" don't show up all the time and it made the default equipment more compatible with the race with this install order of the mods files: version 3, version 4, version 5, Invisible Wolf Fix.

If anyone wants to install the Wolven Anthros race "correctly" refer to this guide: https://www.nexusmods.com/oblivion/mods/46844
If you do so you will likely need additional special armor mods.

I wanted a really unique character, so I needed some body, eyes and hair mods.
- HG EyeCandy Body
Link: https://www.nexusmods.com/oblivion/mods/15802
- RobertMaleBodyReplacerV52
Link: https://www.nexusmods.com/oblivion/mods/40532
- Ren's Beauty Pack Expanded Compilation
Link: https://www.nexusmods.com/oblivion/mods/45635

I opted for the underwear versions.

Phase 1 was complete.

On to phase 2.

I greatly enjoyed the Indigo companion mod in Skyrim, so I checked for some good companions mods for oblivion.
I found these.

- Merchant follower
Link: https://www.nexusmods.com/oblivion/mods/34247
A trader that teleports to you all the time.

- MALEVOLENT
Link: https://www.nexusmods.com/oblivion/mods/17781
- Tears Of The Fiend
Link: https://www.nexusmods.com/oblivion/mods/11598
- Ruined Tails Tale
Link: https://www.nexusmods.com/oblivion/mods/3027

Story-driven companion mods with multiple paths, in my opinon the best mods on the Oblivion Nexus.

- Dairanath Avari - male romance companion
Link: https://www.nexusmods.com/oblivion/mods/35893
- Romancing Ahnassi
Link: https://www.nexusmods.com/oblivion/mods/7636
- Companion Fergus v2
Link: https://www.nexusmods.com/oblivion/mods/37157
- Companion JoVirr
Link: https://www.nexusmods.com/oblivion/mods/39636

JoVirr will comment on the game somewhat. He's not Inigo, but it's nice to have an inquisitive cat around. ;)
Ahnassi is a female kahjit that male characters can romance and female ones can befriend.
Fergus and Dairanath Avari are romanceble regardless of the PC's sex.

Mounts and an evil-looking dog:
- Bettys Kirin
Link: https://www.nexusmods.com/oblivion/mods/46507
- Zira Demonic Mounts
Link: https://www.nexusmods.com/oblivion/mods/40230
- Ushnar's Re-Skinned Hound
Link: https://www.nexusmods.com/oblivion/mods/26143

Next came the Dark Brotherhood and the Arena as my favorite fractions that could be improved.
- Listener Overhaul
Link: https://www.nexusmods.com/oblivion/mods/36002
- The Return Of The Dark Brotherhood
Link: https://www.nexusmods.com/oblivion/mods/40761
- Greed Arena (AoG)
Link: https://www.nexusmods.com/oblivion/mods/48277

The Greed Arena made the Arena a lot better as a few tweaks in the ini file got rid of some annoying limitations such as "no looting allowed" or "wear your arena gear".

Phase 3 mostly involved some mods that made small changes to the game to make it more enjoyable.

- Harvest Flora
Link: https://www.nexusmods.com/oblivion/mods/2037
While it will not harvest flora for the player, it will show already picked ingrediants differently ingame.

- Clear Water
Link: https://www.nexusmods.com/oblivion/mods/3763
While it makes the surface of the water bright, it will remove the fog underwater anywhere in Oblivion, including caves.
I doubt it supports Morroblivion.

- Ayleid Wells Revamped - More Useful Ayleid Well Mod
Link: https://www.nexusmods.com/oblivion/mods/39926
I wanted a permenant increase in mana and not a temporary bouns.

- Unlimited Torches
Link: https://www.nexusmods.com/oblivion/mods/14198
Given how dark Morroblivion can get, I thought it would be wise to get it.

- Jhaeriks Dungeon Fog Remover _Major FPS Increase_
Link: https://www.nexusmods.com/oblivion/mods/40555
I never liked the fog in the ingame caves.

- Soul Gem Spells
Link: https://www.nexusmods.com/oblivion/mods/45694
Want to recharge enchanted gear to the max on the fly? Go for it. ;)

- ryan summon lockpicks (and repair hammers)
Link: https://www.nexusmods.com/oblivion/mods/31224
- Chameleon Ring
Link: https://www.nexusmods.com/oblivion/mods/12114
- Bounty Reduction Over Time (standard version)
Link: https://www.nexusmods.com/oblivion/mods/2052

What can I say? I love sneaky characters. :)

- Oblivion Unlimited Training
Link: https://www.nexusmods.com/oblivion/mods/44392
- Oblivion Septim Spell
Link: https://www.nexusmods.com/oblivion/mods/46053
- no sun damage on vampires
Link: https://www.nexusmods.com/oblivion/mods/42423
- demonocus resurrect spell
Link: https://www.nexusmods.com/oblivion/mods/42919
- Demonocus-Diver's Ring
Link: https://www.nexusmods.com/oblivion/mods/47618
- Demonocus-faster horses
Link: https://www.nexusmods.com/oblivion/mods/48221
- Carry all you want
Link: https://www.nexusmods.com/oblivion/mods/5118/
- Triple magicka
Link: https://www.nexusmods.com/oblivion/mods/7315

The titles should expalin it all.

- Boethia Shrine Custom Race Fix
Link: https://www.nexusmods.com/oblivion/mods/3500
- Custom Race Fix
Link: https://www.nexusmods.com/oblivion/mods/1815
Given that Wolven is a custom race, these 2 are mandatory.

- Passive Beasts
Link: https://www.nexusmods.com/oblivion/mods/1845
Nice to pass by animals without battle. :)

- Landmarks with Wells 1-12
Link: https://www.nexusmods.com/oblivion/mods/46915
- Map Marker Overhaul
Link: https://www.nexusmods.com/oblivion/mods/26389
- Elven Map Redux
Link: https://www.nexusmods.com/oblivion/mods/3002
- Elven Map For Shivering Isles
Link: https://www.nexusmods.com/oblivion/mods/16640

These map mods won't conflict with Morroblivion and are an awesome improvement.

- Horse Armor Revamped
Link: https://www.nexusmods.com/oblivion/mods/46657
- Command Mounts and Horses
Link: https://www.nexusmods.com/oblivion/mods/27957
- Dude Wheres My Horse FINAL
Link: https://www.nexusmods.com/oblivion/mods/3861

Some improvements for horses, now they will finally obey.

- Animated Window Lighting System and Chimneys - AWLS
Link: https://www.nexusmods.com/oblivion/mods/19628
Oh, shiney.

- Daedric Immunities
Link: https://www.nexusmods.com/oblivion/mods/45851
- High Personality Namira Quest
Link: https://www.nexusmods.com/oblivion/mods/13724
- demonocus level 2 for shrines
Link: https://www.nexusmods.com/oblivion/mods/43066

Daedra quests early? Go for it.
Plus now it's worth it completing the Shivering Isles DLC. ;)

- Kvatch Rebuilt
Link: https://www.nexusmods.com/oblivion/mods/15412
- KVATCH REBUILT Walkthrough
Link: https://www.nexusmods.com/oblivion/mods/36844
It should be more compatible on it's own that with Better Cities (I didn't find the latter appealing).

- Glowier Nirnroots
Link: https://www.nexusmods.com/oblivion/mods/39222
It makes the Nirnroot quest easier to do as the plants are easier to spot.

- Camping
Link: https://www.nexusmods.com/oblivion/mods/37197
Portable camp with sleeping bags anyone?

- Companion Tracker Requires OBSE
Link: https://www.nexusmods.com/oblivion/mods/29307
- Move It
Link: https://www.nexusmods.com/oblivion/mods/45968
With so many companions I needed these. XD

- Character Generate Amulet
Link: https://www.nexusmods.com/oblivion/mods/2072

The Character Amulet is a great mod that allows the player to change the race, class or birthsign of their character without crashing the game.
However, if used with Morroblivion it will cause crashes as the amulet is placed in the same spot as the body of the warrior holding the Amulet of Kings. Before using it, use the Construction Set to move the amulet.

Finally, I wanted some mods for greater diversity of wild creatures.

- Mythic Animals
Link: https://www.nexusmods.com/oblivion/mods/29638
- Mythical Creature - Frost Troll
Link: https://www.nexusmods.com/oblivion/mods/44932
- Bettys Creature Creations
Link: https://www.nexusmods.com/oblivion/mods/46303
- Hunting and Wildlife Expansion Beta
Link: https://www.nexusmods.com/oblivion/mods/46163
- Shining Creatures
Link: https://www.nexusmods.com/oblivion/mods/29735
- Lore Creature Expansion
Link: https://www.nexusmods.com/oblivion/mods/7471

Note: Horse Armor Revamped needed Oblivion Mod Manager.

Otherwise, I installed all of the mods manually since some needed files to be selected and copied into the data folder.

The bugs I've encountered so far are:
- The Character Amulet mod will crash the game near the sewers, so it's safer to disable it.
- invisible caribou
I fixed it by deleting the caribou mashes and textures and thus removing them from the game.
They are a nice addition, but I already have many other animals added to the game.
- The game may crash at the Talos Wayshrine.
Reloading a save near it, activating it and moving from the area will fix it.
- The game may still crash at random spots after 2 hours+ of gameplay, but frequent saves are a good workaround.
