Games are still a very young medium, and their perceived inferiority when it comes to telling stories (and evoking emotions) as compared with film -- whether true or not -- is an unfair comparison to make as a result. Hartmann said it would be difficult to recreate the emotions of Brokeback Mountain in a game; if we accept that as being true, does it really matter? Do we need to duplicate everything that film did, but with a game?
And, in fact, in many cases--particularly with games--photorealism is more of a hinderance than a help.
Still think MGS1 is one of the finest example in storytelling and emotion, and as far as I know, we don't even see their faces move.
good graphics + good gameplay > bad graphics + good gameplay
Basing off `Journey`, that game doesn't need to focus on spectacular/groundbreaking graphics but there are many games than can benefit from that advancements of graphics. Speaking in the same context, take film for example. In `The Dark Knight`, where CGI was used for Harvey 2-face, or what ever his name is, `graphics/CGI` was needed to convey a proper feel for the movie that face paint could not match. I don't think `The Last of Us` would be getting as much attention if it were a side scroller.
The Last Guardian is going for realistic animation for the bird-cat creature who's movement and artificial 'performance' will need to be convincing to provide the emotional response that Team Ico and Fumito Ueda are going for.
Although emotion is not that simple, and peoples' emotions are triggered by a number of different things.
Realism in games is fine, but for myself and others like me, it gets tiresome to see every game trying to hand me photorealism.
I'm a cartoon kind of guy. I want to be attached to fun and quirky characters, not gritty testosterone clone #897.
Story, dialogue, character interaction, all these things are more important than photorealism. In fact, I don't think photorealism is necessary AT ALL to bring emotional depth to a game. Great animation will help, but it doesn't have to look lifelike.
