i just read this yesterday, i thought this is pretty interesting read:
http://www.gamasutra.com/view/featur...art.php?page=2
kinda sad how the game practically play by itself to please the casual crowd
i mean something like this (on the 2nd page) :
* hint at the crowbar/door task with dialog
* pop up a dialog box explaining what to do
* flash the crowbar
* when the user clicks the crowbar, it pops up large on screen with particle and sound effects and flies into inventory slot
* crowbar flashes in inventory
* door flashes when crowbar is picked up
* big reward for using crowbar on door
