Right now, we spend PP on a trainer to train in Theoretic Knowledge. But how about learning from books? In Morrowind, if you read certain books, you gain levels in certain skills. The problem with that is that all you need to do is open the book, you don\'t actually have to read it.
I would like there to be books that will raise your Knowledge, only after reading the story. At the end, after flipping throught the pages, there would be a little quiz, just to make sure you read it and deserve the Knowledge you are about to receive. The quiz would be asimple, one or two question multiple choice. If you get the right answer, your Knowledge increases, if you get the wrong answer, you get to sit there and wish you read the book. Now, the quiz is only available the first time you open the book, so there is no cheating.
I think this would be a pretty cool feature to be added in later releases. It promotes roleplaying, and is a nice addition to the current training system.
