Resident ihobo wordstress, Wendy Despain, has recently had an insightful article published over at The Escapist regarding the sometimes soul-destroying "bark".
A bark in this sense being the short, one-liners used in videogames (e.g. "Good shot, soldier!"). Wendy gives an amusing break down of how barks affect players and developers.
Comments on the article should go to the Escapist site, but thoughts on barks and other sound issues in games can be made here.
