Oblivion landscape mods

I thought it might be beneficial to attempt to centralize some of the landscape and location adding Oblivion mods. I'm not an expert though so don't expect too much support, I'll only list ones I've used or seem really good. Make sure you test mods out after you install them just so you know they aren't conflicting heavily with other mods you may be using.

Mods with new lands:

Nehrim - A very good translated total conversion mod.
Andoran Axis - I don't know much about this but it's got it's own worldspace.

Dibella's Watch - Quest mod.
Windfall - Large quest mod.
Carnac Peninsula - Japanese worldspace mod. Has a little kingdom you reach by boat.

Mods that improve Cyrodiil's cities:

Better Cities - Improves the cities and has an 'open' module if you wanted it. Be careful with armor mods adding to the IC, make sure they load before BC, also needs UL patches. Recently got an update and subsequent patches for it.
Open Cities Reborn & Classic - Removes gates to cities. Reborn changes their layout as well.

Open Cities patches - I doubt these cover all conflicts but who knows.

Cyrodiil Rebuild - Neat looking mod by the Andoran team. I haven't used it since it would surely conflict with the mods I'm using.
Cyrodiil Rebuild II: Imperial Capital - Same as above unfortunately. I use Better Cities.
Skingrad Outer District - Adds a little slum outside of Skingrad.

Mods that add new settlements or geography to Cyrodiil:

Unique Landscapes & it's patches - Makes Cyrodiil's geography much better.
Shezries Towns - Adds some nice towns. Make sure to enable the UL patches for Ravenview and Lakewood.
Avalon Project - Japanese mod that adds a kingdom to Cyrodiil. More info here.
Roads of Cyrodiil - Adds new roads & bridges to Cyrodiil.
ImpeREAL Empire - Unique Forts - Adds huge forts alongside somde Cyrodiil roads. Needs UL patch.
Dragon Captions - Villages - Adds some villages around Cyrodiil. Needs UL patch.
Imperial Navy - I use tes4edit to delete the NPCs for better FPS.

QQuix - Rock rock rock your ship - Makes most ships bob around.

All Things Alchemical - Got this from a Loverslab thread. It restores a burnt down roadside inn.

Settlements of Cyrodiil - Little mod that adds a couple farms.
Milewood - Adds a pretty large town east of the IC. Didn't seem to require any patches when I tried it.
Arthmoor's villages - Also check out his various patches.

Feldscar
Vergayun
Faregyl Village - Has a patch for Elsweyr but it may not work with the new version.
Frostcrag Village
Reedstand
Urasek
Sutch
Gottshaw Village Expansion
Molapi

Hesu Mod Collection - I haven't used this but anon said it's pretty good.

House mods:

Flying Island House - Comfy house with useful teleportation pads.
Swida House - This mod destroys my FPS but it's pretty comfy.

Village enhancing mods - These often conflict with each other and probably all need patches for UL or other mods.

Region Revive - Lake Rumare - This one adds a couple of settlements around the IC isle as well as improving Weye
AFK Weye - Seems to add a chapel and some interiors to Weye.
MTC Expanded Villages - Expands several of the existing villages as well as Weye. I haven't used this mod as it needs several patches to work with other mods. I'll list them.
