i request a Helms Deep mod, if playing as Human take the place of Aragon, if Elf Legolas, if dwalf Gimly, or an outsider who turns up just before the Battel,
That sound really cool, but you will need a whole TC mod team to do a LOTR mod...
its been attempted, but turned out impossible due to oblivion's limited cells. there was a team trying to convert Middle Earth into oblivion but it was too big and makes oblivion crash. you could ask them just to release helms deep part of it.
Well oblivion is a third/first person RPG while middle earth is a RTS so I dont see howe you can comperae them.
It wouldn't have mattered if the LOTR mod would've worked with Oblivion or not. Tolkein Estate would've told them to stop anyways; they did the same with the LOTR TC with Morrowind sometime ago.
And LOTR could make a good RPG. No one has attempted it though on the computer, just on boards and paper and pen.
Helms deep is possible though. Some people have released some minor things LOTR based, like Sauron's armor.
