I like the idea. Used to spend ages on Warhammer Online trying to fill up the codex on that.

Other thing that could kick in the 'immersion' (the damnable word!) is a few more moving objects in the scenery. Everything is always so static, I was happy to see those machines displayed in the beastmen stronghold, heck, just looking at the sparkler balloon (floating over the lake right now during the event) in Gridania felt strange because it was moving.
