I really like the first idea. WoW had little hidden books all over the place in towns and dungeons and that was the only place you could read them. It'd be nice if there were books about the world of Hydaelyn that you could place in your house for going back and reading.

Not saying the other ideas are bad or anything, they're just something I'd expect to be implemented at some point in some fashion or another. I really want to see the first idea come into fruition though.

Just to add, I liked how each furniture had bonuses in FF11. I like to fish, so I hope there'll be furniture again that boosts your fishing skill and whatnot.
