Elder Scrolls Online studio head says Skyrim completely changed what people even thought an Elder Scrolls RPG was, so the MMO "had to radically change lots of things"
The Elder Scrolls Online's Matt Firor considers Skyrim, which launched before ESO while the MMO was still in development, "very much a virtual world game just centered around one player." I know this because he told me as much during our interview at Game Developers Conference (GDC) back in March. He also says that the launch of Skyrim had an absolutely massive effect on ESO and ultimately led to radical changes.
