I'm sure they have their reasons, but the in-game economy has been out-of-whack for a little while.  Content ranged from stupid expensive to basically free. 
  
The new structure adds value to the bundles, and better focuses in-game gold as the single in-app currency for things like consumables and treasure chests.  The old way was generous, but Pathfinder's add-free hybrid F2P was a little unusual for commercial games. 
  
To be honest, requiring a little more cash is probably best for the long-term viability of the game.  There's almost no chance of seeing Skull & Shackles get developed unless you can convince MrBishop to be paid in Pathfinder Gold.    
  
  
I have 20k if he wants  
  
I'm tempted to buy the goblins one, but was thrown off with the lack of gold option.
