The Elder Scrolls Online might be transitioning the series to the multi-player market for its first time, but that doesn't mean everything you do will require groups. Nope, far from it.
Matt Firor, game director of The Elder Scrolls Online, told Game Informer during an interview that the game will emphasize the player's role in the game world, much of which will require a focus on single-player to develop. He stated:
We have a whole part of the game that is 100% solo, which is the main story, where the world focuses on you. You're the hero, and everything you do is solo and the world reacts to you that way.
So the leveling experience is solo... and he mentioned mentioned in the interview that many of the quest areas will be instanced. That sounds awfully familiar.
Oh that's right, Star Wars: The Old Republic went for the same thing. It's a shame its scale and sense of community was jeapordized because of it.
Honestly, I would have expected the series' first hit at multi-player to be more bold. Back when The Elder Scrolls V: Skyrim came out there was a lot of talk about how great it would be if co-op were available. What's the purpose if the dungeons and core story components were solo-based? That defeats the purpose in my eyes.
