A-> If the player is bashing away at the keys franticly, they are most likley excited or in fear of somthing in the game.
B-> If they are being cautious pressing little keys and moving a joypad/mouse slowly they are most likley quite nervous about the situation.
This lead me on to think how a game could be programmed to respond to the players mood, making it more exciting for them. Like if the player is in mood A (shown above) some hardcore rock music could kick in or even triggering more enemies to fly at them, the game could respond in any way which makes the player more button bashing crazy.
With B it could kick in some eerie music to make it more suspense.
The problem with the above is that you cant stage a game very well, if a player is just running around firing at random boxes and going crazy and yet there are no enemies, it doesnt make sense to kick in some hardcore rock music (althou it would be cool). Plus you would lose a sense of control to the game, it wouldnt allow you to make the player tense, when you wanted them to feel tense.
Im not sure if this has been done or even used in any games before, it was just an idea i came up with today... Any comments?
