So far (besides the Shivering Isles) I have the following mods that adds new land areas that requires one to enter thru a portal or door to enter!

Nascosto Isles (version 3)
Midas Magic (Has some different land/world areas to explore thru via a crossword puzzle activated portal!)
Duke City (second beta version that actually works)

Now I'm looking for more mods like them that actually lets you explore new worlds (ones that are accessed only by entering/walking thru a door or stargate/oblivion like portal/or boat/ship ride, where you click on the boat and you teleport over to said world space, or other teleportation ways! And I'm looking for only such mods that actually works and has good reviews from the TES-IV: Oblivion players! And please provide me links to said mods! And please don't list new land mods that takes place in Tamriel that can be accessed by simply walking to there without walking thru a door/portal/boat ride (I.E. Elsweyr Deserts of Anequina, for example)!

I'm only looking for the best ones in that TES-4 mod category, btw!

:P Seriously. With all the things you're suddenly looking for, and you're "must be the best" criteria, you'd do better to use a little initiative and look for yourself.

I was looking thru the "New Land" category, and it seems to be mixed with both lands that takes place in Tamriel (meaning that you can walk straight to there once you remove the invisible border wall in the .ini, as well as the lands separated away from the Tamriel/Cyrodiil/shivering isles world spaces! I was shocked to even see some of the Unique landscapes mods listed in that category! I only wished TesNexus would divide the "New Landscapes" category! Now to think about it, I may post the subject there, as well!

You can do a search of the New Lands category for "new worldspace". That should bring up most of the relevant mods. Then just sort by ranking or by donwloads.

Also, can you do me a tiny favor and use a period once in a while? No way are you this excited for mods

You have Mesogea somewhere on forum's 1st page.
