WRPG's are more non linear therefore they are less repetitive, you have impact on the world and characters around you and your choices make a difference , plus the characters are shaped by you therefore it is a truly role playing experience.
JRPG's do follow many schemes, but what i enjoy in them is characters and storytelling they just have so much charm about them, i do hate grinding for me necessity of it in some games just kills the atmosphere.
For me most of FPS's are too heavily multiplayer oriented (i dont play online) which makes single player crappy, also stories tend to be average at best. The shooters that are enjoyed are games like Operation Flashpoint or Ghost Recon, i like tactical games , not mindless shooting like CoD (i know its not mindless but i kinda see it this way)
My biggest grudge with excellent RPG games like Fallout 3 or Mass Effect (which i completed today!) is that they turned fighting into shooters. RPG's are my favourite genre, while shooters are kinda games that i only play once in a long while
