I just switched over to JP iTunes for the first time in a while, and I may have made a rather appalling discovery about Demons' Score
$6.99, but game content locked behind IAPs; game content IAP total cost is $39.91, pushing total cost of ownership to $46.90.
1500 yen ($19.22 in today's currency), no game content IAPs.
Even after having paid the base cost of the US version, it would still cost me less money to rebuy the whole game on JP iTunes twice than I would spend purchasing the US version's IAP unlocks
Can someone with the Japanese version confirm this?
EDIT: A poster at TouchArcade who resides in Japan
confirms this to be true. Apparently I'm not the first to discover the pricing discrepancy either; this post was made four days ago. Also amended cost of US version; originally understated.
