I meant in a few months after they recover, some of them probably wont want to touch video games ever again, and those that will still want to play probably wont be allowed to.
As for Asuna, that part is confusing. Kayaba didn't seem to have lied about anything, and Asuna should've been killed after she died, yet she appeared after the game was cleared.
But if i recall correctly there's an item that allows you to revive a player if its not long after they died, so maybe clearing the game saved her.
