With the 64 bit update Incoming what are you hoping to see change? I am thinking we may get a graphic overhaul. I hope we can get larger worlds at last prehaps update some of the smaller EP/GP worlds ...
Game is indeed have a support for 64 bit long time ago, but they also cater for the 32 bit user so they probably also had to be careful when and what to add to the game, remember the Del Sol Valley small world, I think when they finally stopped supporting 32bit we'll see an improvement in the future content.
