The Elder Scrolls Online Will Receive Frequent Updates, Main Quest is "a Launching Point"

Speaking with Shacknews, The Elder Scrolls ONline creative director Paul Sage, explains the team's plan for the main storyline and why they're shooting for frequent content updates:
"We watch everybody in the market, but I'm a big proponent personally of making sure we keep a high frequency of content releases," Sage said. "A big part of our plans is the future of the game. We always want to make sure there is something new right around the corner. Our plan is to have new content coming out on a really frequent basis. We want to make sure that people are really into the game and get to experience a lot of new things. We will have a lot of content at release, but I know that players are amazing in their ability to chew through content quickly, so we want to make sure there is a constant stream of goodies coming to them."

Sage said his experience as a developer on Ultima Online reinforced this theory. "The more frequently you update, the more the players like it. Players are more engaged. I think it is an issue of trust in a lot of ways. They know there is going to be a lot of new content coming in."

He added that, while the main storyline in the game may end, it is also a beginning. "We've talked about Molag Bol stealing your soul at the start of the game, but that's a launching point. You'll wrap up the main story in The Elder Scrolls Online at release and that leads into an even bigger story."
