Games can not only control anger but other emotions as well. Such as depression, all you Final Fantasy players can relate. Final Fantasy VII, I'll just give one example of the sad plot line because there's to many to mention. Final Fantasy VIII is not as sad as its predecessor as overwhelmingly cool. The whole planning and carrying out the assassination of the evil queen, the attack on the garden with people running everywhere.
Every moment is almost too much to bear.
Games can be aggravating, depression causing, ulcer causing, funny and down right disgusting at times.
