Yeah, that frustrates me a lot, too. They almost had it right, that they need to go beyond realism to make truly good-looking games. But in practice, they say that only to show you the most boring-ass graphics known to humanity. I don't need your pebbles to cast shadows. I can walk outside and find a pebble that casts shadows in a minute tops. Make the pebbles cast light instead, that could look cool. Or make them cast a basketball game. That's at least something, I haven't seen yet.
