Shouldn't it be CG? 3D isn't exactly the right term, iirc.
Yeah. Due to the technology of motion capturing, doing scenes like that is going to be a lot easier. You're still going to need stock 3D models, the backgrounds, choice of music, camera angles, and other fun stuff.
I wonder how many companies use screen capturing when making FMVs?
