The game is awesome. So much fun to just play and explore. But there are some minor issues:
By default, the game maps crouch (for sneaking) to L3 (click left stick) and sprint to B. This is flawed because one must remove their thumb from the right stick everytime they want to sprint (which is often, given that sprint consumes stamina which drains as you sprint) thereby removing the ability to control the camera every single time you want to sprint.
The fix is to map sprint to L3 (like most games) and crouch to B. The ability to control the camera while pressing a button to sprint trumps the ability to control the camera while pressing a button to crouch (especially given that crouching is a used significantly less than sprinting)
There should also be the ability to quick-drop a currently held bow, shield or sword with a new one on the floor by holding A whenever the inventory is full. See Borderlands as an example. If your inventory is full and a better bow or shield is in the field that you want to pick up, the current way to pick it up involves going into the menu, selecting the desired item to discard, clicking 'drop', exiting the menu and picking up the new item. It's slightly less annoying for swords, which can be thrown (literally) by holding the R button, but it's so cumbersome.
