Earlier quoted context omitted.
World-of-Warcraft-like MMO games allow for "character customization", but on a moment-to-moment basis, character models are mostly static. You can read an explicit display of emotion if they choose to "emote" one, but there are no continuous subtle cues about how a person is continuing to feel about something. Now, one of the interesting things about VR is that, provided your perspective is attached to an avatar, the…
Except you're face is going to be covered with virtual reality junk, and all it does is display something a normal monitor or TV can. Reading your facial expressions requires nothing more than a webcam. And the whole thing I think is just a gimmick that doesn't add much value (both VR and facial expressions.) Additionally video game characters look really creepy when they try to do facial expressions.
2. Modern graphics technology has all it needs to generate realistic expressions on characters. Modern video-game characters instead look creepy because they're replaying a small pre-made library of expressions that don't usually fit the situation very well. If the character's face just mimicked the tension in the muscles of your own face moment-to-moment, this problem would disappear.
3. The argument that facial expressions (or body-language in general) doesn't add value is refuted explicitly by the fact that people prefer meeting in person, to meeting over video-chat, to speaking over the phone, to having a text conversation. The only thing each rung of that ladder adds to the previous is body-language-based interaction.
But these are all beside the greater point: the feeling of being in the same room with someone is necessary for the emotional regulation of your relationship with them. Skype doesn't give you that. VR, eventually, can.
