too culturally different in terms of gameplay , difficulty ,motif or concept.
and what makes that relevant to region locking?
-I can read Japanese just fine.
-I play and finished the Japanese ver. of Catherine which is much harder.
-I like playing quirky Japanese games much better than the AAA scene.
The only valid reason for region locking is region pricing.
Like what happened for Pesona 4 arena, the first disc based region locked game for the PS3. This was done to prevent Japanese people importing the identical US version because it was cheaper and it will hurt the sales in Japan.
Other than that, any other reasons are just bullshit.
