Would you think interesting having some important information about the game's richness being accessible only by in-game books that you can purchase or find?
Some examples of certain information being only accessible through in-game books includes:
- Books revealing where certain plants, animals or other resources linger about.
- Books revealing sites of interest and possible connected quests.
- Books revealing how certain things in game actually work, like smiting, alchemy, skinning etc.
- Books revealing information on that unique items or creatures that you've never heard before.
Or would you prefer having in game, from the very start, a huge library of information where you can access at any time? OR! Having this huge library of information being slowly written as you "read" books about endless subjects? When I say "read" I actually mean just using that item which will injecting data into this library of information, like a journal.
Maybe you prefer another approach? What say you?
[EDIT]
Sorry! I forgot to mention. Everything does change from game to game, well, whenever the player decides to generate a new world in which a numeric seed will be used to generate everything from scratch. This includes generating the planet itself (landscape), items, quests, creatures etc.
