Jrpgs don't have to learn jack from wrpgs, rather they need to evolve by striking off on their own path and creating new experiences. In this regard we are already seeing changes in the form of Valkyrie Chronicles, End of Eternity and the incredible Demon's Souls. In fact with the exception of Fallout 3, wrpgs can take a flying leap. Everything from the stories to the ugly aesthetics, characters, to the throw away morality systems are a turn off.
