This goes to the heart of the role concept.
Most people would agree that it's more rewarding (basically more fun) if in NWN2 you could really 'hide' (move your PC around, putting it behind pleaceables, move from one shadow to another, dropping to the ground if the orc is watching, etc) than just hitting a 'hide mode' button.
The problem is, is it you that's hiding or your character? wouldn't that let a wizard hide as good as a rogue? if you are skilled with your mouse, would you have to make mistakes on porpouse if your character has few points in hiding?
If we go further, and instead of a mouse we use 3D glasses, virtual gloves and all that, could you physically do your blows with the sword instead of throwing dice? would you have to be a matrial art expert and start sweating in your room in order to role a monk?
The funny part of the 'do it yourself' idea conflicts with the basic idea of role-playing a character that it's not you and that has different skills and abilities than you do.
I guess games will fluctuate both sides of the balance between those two playing modes, swinging around the equilibrium point, stretching from player-only skill (counter strike) to character-mostly skill (D&D, besides trying to role-play a very smart PC when you're dumb).
