The Elder Scrolls has been known for making great games since the beginning. With no flops and only great titles, each one with the highest end graphics and engines of the day, the Elder Scrolls Online looks to become another hit. Both similar to their previous titles in world and occupants, becoming an online game means some significant changes in the world of the Elder Scrolls.
Is it an MMO?
Then no, it can't be more successful.
I hope it's innovative, or at the very least somewhat original. Skyrim felt really stale really soon.
