First of, I'm a diehard Bethesda fan. I'll never forget my early experiences with the Fallout series, and their other releases like Daggerfell and Morrowind, which were, in my opinion, game-changers (pun intended).
Despite the many glitches and slow-to-render maps, I believe that Skyrim was, and is continuing to be, a huge success for the company. However, I don't really know what to think about their new MMORPG, Elder Scrolls: Online.
I don't know what to expect, but I'm not sure that the RPG-heavy company would make a very successful MMO.
