ESO feels like a mix of MMO and TES. It isn't completely a single player TES game. It isn't completely an MMO. It feels like a fusion between the two. When Destiny and Star Citizen do exactly that in their games, they will get praised for it. When ESO does it they will get the hate bandwagon.
The blanket statement that Skyrim is better than ESO is false. There are many things ESO does significantly better than Skyrim, like progression and story. There are several things Skyrim does better than ESO like exploration and production value.
I was more immersed in the ESO world than the Skyrim world. Expect for those pesky people running around.
