The first part of the adventure pack will come as a free download. All of the game's subscribers will be able to sink their swords into a new zone, fight new enemies, and so on. There will also be some new quests in this area for all players. Some of these quests will flesh out the lore behind the game's dark elf race and at least partially explain what has transpired in the 500 years that lie between the original EverQuest and EverQuest II. If players want to continue down this story path, they will have to pay what's been described as a "small fee" to download the rest of the adventure pack's content and continue on. Players that choose not to participate will still be allowed to adventure in this new zone and experience at least some of the new content. If the idea's a hit, SOE will likely follow with more adventure packs in the same vein. Some may continue where an existing adventure pack leaves off, though it's also possible that future content offerings may tell an entirely different story. If the price is right, EQII's adventure packs could be a cool solution to provide small chunks of more involving content on a more regular basis than you'd expect from the previous model of occasional expansion packs. That said, SOE certainly hasn't completely eliminated the concept of a retail expansion for EQII, either.
