Al that work to be realistic, and then these ridiculous one-linere like "I thought you'd never ask" and "you boys'll get a kick out of this". You'd think with all the money they're spending on visuals they could afford a screenwriter or two.
"Say something to the effect of this, when this thing happens on screen, but phrase it however you like."
Visually stunning, but no matter how realistic it is, you're killing the chance of enjoying it because you go "Nobody would say that", and it also doesn't sound natural.
This is why I enjoyed the Fallout games so much. Even the earlier ones like 3 and New Vegas that weren't realistic looking had fantastic, believable dialogue.
