I think some fans will be rather unhappy that you said that...
But the numbers haven't gotten nearly as big for the Elder Scrolls, besides, the Elder Scrolls doesn't have "final" in its name, calling a game a name like "Final Fantasy" seems like false advertising when the series manages to run for... I don't even know how many Final Fantasy games there are any more.
But in any case, the numbers work fine for me, although I wouldn't actually care if they dropped them as long as I still got the game I want, but why get rid of them? They work just fine, and they make it clear that this game is intended as a sequel to earlier Elder Scrolls games, as well as making it easy to work out their chronological order, sometimes if you have sequels that are not numbered, it becomes easy to get confused as to which one comes first, especially when there's a lot of them.
People who take issue with that are too biased and don't understand the reason for the comparison. Also, final fantasy's final has nothing to do with the game, came about because squaresoft was outta money and they thought that game was the end of their fantasy of being game dev's, so they called it that. It sold big time, and it became the name for their marquis RPG titles from then on, not that the games are even in the same universe (with a couple exceptions involving spinoffs/direct sequels)
As it is Im ok with that comparison because of the fact that Elder Scrolls seems to the THE Western Fantasy RPG, where like it or not, the FF series is the big JRPG series as far as the US is concerned.
That said I don't really care if they number it or not, I really just want to see the rest of the world, and eventually have the megagame with all the regions in one! Yes, massive game, hours and hours of walking... wait.... hmmm....
