Player outrage over the issue is unsurprisingly at peak volume, with the two main points of contention being that the adjustments were not announced ahead of time in any format (and indeed, even Square-Enix’s own staff seems to have been somewhat surprised) and that the price adjustment fails to take into account different incomes in different regions. It’s not the first time in recent days that we’ve seen some dispute over localized pricing for different regions, which if nothing else goes to show the difficulty in operating a global game with servers open to all regions.
