The JRPG genre has become stale. It's always the same tropes and cliches. With WRPGs, you have a wide variety of stories, settings, etc. You have Mass Effect with space exploration, Fallout with Post-apocalyptic, Dragon Age/Elder Scrolls with medieval/fantasy, Deus Ex with Futuristic, etc. WRPGs cover a wide range of locales and worlds while, as big a fan as I am of JRPGs, stay in the same realm of teens saving the world with the power of friendship.
