This is cute and retro! But I think training only on GoldenEye undersells the concept a bit, since their world model inherits the N64-era graphics from GoldenEye, which automatically makes it look dated.
They don't want to push the envelope too far in the first release and Goldeneye level graphics are more forgiving towards flaky textures and wonky physics. Not to say what it is isn't already groundbreaking.
