Myös neljännesvuosittain on tulossa uusia kausia pitämässä mielen virkeänä.
"But, you know, it's years and years. That's the thing we're focused on. When you look at the launch of the game and this first season, we see that as building a foundation on which we can build for the future. So, as we look at our quarterly seasons, and we look at our annual expansions, those are the things that we're really focused on for our live service."
"We've got plans, we have storylines that go well into the future. We've got plans. We're always leapfrogging our seasons, and leapfrogging our expansions, so it's something we are going to do for a long time. We're excited."
