I've got to say, I think people forget that this game is their job. They need to make money so that the company prospers, and so they don't get downsized. We might want them to cater to the small minority, but I doubt the spouses of the developers would like to hear "We put out a game that the diehard fans love. Where's the newspaper Jobs section?"
It's unfortunate from our perspective, but they have to put out a game that will sell to the silent majority.
Also however, Elder Scrolls has cult status. They thrive on their cult status even if they are making the game more marketable to consumers.
it's been done before... here are the steps of an unsuccessful way to manage cult status in video games
1) start making games that cater more towards the masses, and less towards devoted fans
2) More money is made... so continue making games that cater more to the masses
3)The game eventually passes the critical point where cult fans no longer look forward to new installments of the series
4) losing cult followers doesn't effect the money so much now that there is such a large target market for the game.
5) the games then becomes unoriginal and stale through, and the fickle consumers who the company originally was trying to attain eventually lose interest.
