I wrote an article in portuguese about it and as I was too lazy to translate it, I would like to post a lesser piece of the thought.
In a few words: can we just do anything we want just using the magic words "it was ic" and "it was a PC's action"?
Can we accept the idea that only NPCs have to keep the genre? Is it ST's exclusive job to read the books, genre packets and all that stuff just to let a PC come and do it the other way, freely and without consequences?
Please, stay tuned.
