As it turns out, a whole lot has changed. We've mentioned it on our podcasts and in our posts, but Morrison is keen to continue to emphasis the improvements and updates here as well. The latest update has quite possibly been the biggest and equally subtlest improvement yet, as it completely reworked the item system to be less obtuse and make items more desirable.
But you really don't need to take Morrison's word for it, since the two free weeks campaign is in full effect. You can be sure Massively is jumping head first into Hyboria to get a taste of AoC's new flavor.
