Wii was great multiplayer fun. We literally spent half days playing Wii tennis with 2 or 3 people. I assume that VR will be much better (only used DR1 and cardboard and of course they aren't too compelling), but does meaningful multiplayer VR exist yet?
Edit: And by multiplayer, I mean everyone in the same room multiplayer. Social multiplayer?
You're right - Wii's strength was local multiplayer, whereas Vive is more of a conventional online multiplayer, considering you need a separate Vive for each person. If you happen to have 2 Vives nearby with enough space, I imagine it's fun, but you're still inside your own world, so a mic+speakers/headphones is all you really need.
There are some games where another person can participate outside VR (Keep Talking and Nobody Explodes), but it's not really the same at all.
