What is the difference between a JRPG and a WRPG?

jRPG = Made in Japan, made by a Japanese developer, anime like appearances/cartoonish - focuses on the Fantasy theme more than Medieval themes/etc themes.

Examples
-Final Fantasy
-Star Ocean
-Dragon Quest
-Pokemon
-Breath of Fire
-Persona
-Kingdom Hearts

wRPG = Made in the West (i.e. NA/Europe), made by mostly English Speaking developers/Other (not sure how to put them as) developers, "Realistic" appearances/Dark themed, more focused on Medieval themes and sometimes futuristic.

Examples
-Elder Scrolls
-Fallout
-Mass Effect
-Might and Magic
-Dungeons and Dragons
-The Witcher
-Star Wars Knights of the Old Republic

I still don't get why people write JRPG/WRPG as jRPG/wRPG. The J/W part is the part that should be capitalized.
