Video game engines can handle the kind of complexity and realism you can't put into a movie - yet. But games are getting better and better - I imagine a day where you won't be able to tell a game from a movie, with great A.I. animation and photoreal, interactive environments, etc.
The good thing about recording everyone separately is it gives the directors more control - they can change one character's lines in a scene without having to re-record everybody, and the story changes a lot before the movie comes out.
Of course, even if the directors like my ideas or the designs I do, they may end up changing the story so much, that those characters have to change, or get cut out altogether, and that's just the way it is. Sometimes the directors are designers themselves, or they want to work with a character designer who will do things in their own distinct way - sometimes the most important thing I do is figure out what they don't want to do, by experimenting. Either way, whether they use my ideas or not, I get paid, so it's all good.
I think it's really cool that videogames are getting more and more sophisticated and believable, and that people who worked on movies are being asked to art direct and design video games and characters, so they look better and better. When I see Jurassic Park on the screen, I predicted that games would be able to create a virtual experience that was just as real as the movies - we're not quite there yet, but it's getting better all the time.
Ironically, I must admit that I have an easier time (myself) playing games that are really simple and non-realistic - like the games I grew up with in the 80's - I tend to get lost and confused when the games get too complex! But I enjoy watching people who are good at playing games. I really enjoy playing games like Guitar Hero, where you feel like you're a great musician even if you're not.
Maybe if audiences all over the world would check out animation from other countries, filmmakers would be more sophisticated and experimental.
Here's my take, for what it's worth: I think that a lot of people in the US, as well as other countries, have the idea that animation is primarily for children, and kids like to be entertained! And animated films here tend to have crazy fantastic situations that would be difficult to do in live action, like with talking animals or monsters or whatnot, and that lends itself well to comedy, I think.
