The ability to write and publish in-game books. I feel like this would be a huge immersion factor to the RP writer types, and there are a lot of us.
I'm guessing each book would have to be run by an official 'in-game book publisher', or team at ZeniMax - I really can't say how it would be done, but that's to be left to more important people.
Think about how it would feel to have your very own in-game book being sold by book traders. Your name on each copy. Think about the possiblity of fans. It's something deeper than being "famous" around a group of
people for being a good raider, or PvPer, or being a great trade chat troll. Something to make the role-players a large, known part of the ESO world.
I'd love to hear some opinions and ideas on this
Oh, and before I forget to mention it, the Player Journal mentioned in te title is self-explanatory. Something we could write our adventures or passing thoughts down in.
