Well, I am a game developer myself (indie MMO), and I know how difficult it is to make a game. I think the Nehrim team has done an absolutely amazing job, the complexity of the game and the amount of work involved is overwhelming. I didn't like Oblivion at all, in fact I quit playing after 3 hours, because I thought it was missing something.
When I heard about Nehrim (on Reddit), I said, well, WTH, I'll give it a try. And I am very happy I did, I am playing many hours a day for 5 days now. If only it had an English voice pack, it would have been probably the best RPG of 2010, except maybe for Fallout New Vegas.
So anyway, what are your plans next? Do you plan to work on another mod? If I were you, with such an amazing team, I'd try to make our own stand alone game, possibly by using Ogre3D or something.
