Dedicated fans will have the option of ponying up for "ESO Plus" memberships. Available in 30, 90, and 180-day durations, these will offer access to all future DLC, which Bethesda said will consist of "game packs with optional adventure content," like zones and quests. Access to these optional areas will be lost if and when your membership expires, but any items or rewards earned from those areas will be kept.
ESO Plus memberships will also provide "character progression bonuses," and an allotment of crowns, the new in-game currency that will be used to purchase "convenience and customization items" like pets and mounts, as well as the aforementioned DLC, which will be available separately from ESO Plus memberships on an a-la-carte basis.
Now I will never play this game.
