JRPGs stories are usually recap of old care bear episodes, always going off about the power of friendship and some other shtuff. Also, the dialogue contain about 80% more "shocked" or "in-pain" groans and moans than in WRPGs, a lot like in anime and it is usually cheesy as fudge.
WRPGs are RPG for manly men. prime examples are Mass effect and Skyrim. I mean, all you do in those games is fuck bitches and get money. Protagonist in JRPGs couldn't get laid if the entire universe depended on it, probably cause it's usually a bunch of goddamn 8 to 14 year old kids saving the world.
