Could also be called "the Resident Evil approach to developing the plot."
This is a feature I found in, as I said, RE games, but also other games by Capcom such as the RE-inspired Dino Crisis and Onimusha. Now, regardless of...dubious writing quality in the cutscenes of these games, the files tend to be the most lamented element of the game's stories on on places like SomethingAwful. Having a document that explains backstory or other important things tends to be looked down upon as a very lazy and bad way of developing your narrative.
I guess I can see this but I never had a problem with it and was baffled to find so many people think this is so terrible. It got me thinking though about FinaL Fantasy XIII's Datalog or Xenosaga's Database or Star Ocean's Dictionary.
And so:
1. Do you think files in the RE style are poor ways of telling a story?
2. What is your opinion of in-game encyclopedias that contain critical plot info that you might not know of if you did not read them?
