Yes i would like to know if splitscreen is possible on the elder scrolls online.

I honestly don't think it will.

Nope, the game is an MMO, not any normal multiplayer game.

There would have to be several limitations; players of the same alliance could only share a screen together and more importantly, they would always have to be the same cell at any given time. I'd expect visual degradation as well.

As cool as it would be, I don't see it being an option.
