I completely get that sense of achievement and euphoria surrounding accomplishing something difficult that you have worked hard for. I get that same feeling quite often playing games as well. I agree that our games should make us want to jump up and down, pumping out fists in victory when we deliver the final blow to our enemy and save the kingdom or what have you. There is nothing wrong with that and that experience can be developed and engineered through game design. Reading this very eloquent individuals letter, I believe his longing for completion dips further than those experiences, and even if I have him pegged incorrectly there are people out there that hang their very existence on striving to find a "purpose". You can manufacture an experience as you have stated and "empathize" and identify with a character but when you are striving to find something to cling to in your real world life... Finding a "purpose" in video games is not a healthy option. Surely you would agree with that?
