Eww, not even 3 minutes in and I hate everything he's saying. This 'player authored stories' concept are the kind of games that bore me to death. Games that are made with the express intent of telling a story or with providing the player with a specific experience are the best kind IMO, the kind I love the most. I don't want to make up a story as I play, I want to have a specific experience that the designer wanted me to have. I want to be immersed in someone Else's creation. I want clearly defined rules for me to learn and ideally manipulate to my advantage.
I don't mean games need to be loaded with cutscenes, Demon's/Dark Souls and Shadow of the Colossus had very little but they were still tightly focused and provided a tightly controlled experience. Games like Skyrim are a big blurry unfocused mess to me, and while there is some fun to be had there most of it is very dull. In Skyrim's case this was made even worse by its terrible combat. I am more interested in Kingdoms of Amalur because it actually has good combat and is pleasing to look at, even though its a similar formula.
I'd rather play a game than watch a movie if they can provide a similar experience in terms of story, characters and emotions. Games are way longer than movies and I get to take over during the action scenes.
Nearly all my favorite games are heavily story driven while also providing a quality gameplay experience, like the Yakuza series for example. God of War is another, I rented it and loved it, but the reason I went out and bought it and replayed it numerous times is because of the story. Without that I never would have touched it again. Same for Uncharted 1. I rented it, beat it, and bought it all in the same day and have replayed it over 20 times. Strip out the story and characters and I'd have never touched it more than once.
I love Deus Ex but not for the reasons he's talking about. I love it for the same reason I love the games I mention above, and frankly I'd rather dispense with the dialogue menus and such, I want choice when it pertains to gameplay, like combat tactics, equipment and exploration, but not when it comes to story.
There are games I love purely for their gameplay and not story or experience, but those are very rare. DMC, God Hand, Bayonetta and Vanquish are all good examples, but even those are improved by their stories, as batshit as they may be, because they provide context for the action which is still very important. The only games I can let slide with little to no context are 2-D platformers and scrolling schmups.
I respect Jaffe but I disagree vehemently with everything he's saying. I think he' selling this medium short. Video games have unlimited potential as an artistic medium where everything is possible. There's no one right or wrong way to utilize it and every designer should make the game they want to make.
