Thanks to everybody for that very nice discussion in the last post! For the record, I agree that the "loss is required for great art" hypothesis is not tenable. Suggestions, that have been given in the last post, to replace it with "conflict" or "change" are good. But they might also be a bit too obvious.
At least we all agree that great art induces great emotions. But let me ask you a few more questions:
1) Do you think that narratives are the only way for computer games to create great emotions?
2) Do you think that the dominant emotion induced by all computer games is that of "gain" / "achievement" / "fulfillment of dreams" ?
3) Are there any computer games that, in your opinion, are equal to art in other domains?
Before you answer that last question, refresh your taste of great art here and conclude it by putting your headphones on your ears, double the volume(!), darken the room and listen to this interpretation.
