Well, the price of gold went up for European and Canadian players today on IOS . I've heard it's gone up by as much as 50% in some places.
Believe it was an Apple issue and not GREE (for a change).
I'm in the UK, and £92 for a vault is frankly ridiculous. 115 Euros in other member states.
GREE, you need to act - this will be the death knell for your games if a large ratio of your paying customers are priced out by this insane increase.
