ArcheAge, but that isn't stopping fan sites like ArcheAge Source from digging up lots of interesting stuff on the Korean sandpark title.
The site has a wealth of information covering several aspects of ArcheAge's fourth closed beta phase, including multiple skill guides, lore, and various videos. If that's not enough for you, there's also the latest beta patch notes that are available via Google translate. Check them out to learn more about siege ladders, the game's family system, and importing your own graphics for cloaks and ship sails.
