I don't play the game, but I've done it with comped tickets. There's absolutely nothing that would prevent you from handing over tickets to another person. You have to give ID at will call when you pick stuff up, but the tickets themselves are physical, and could be handed off just like anything else.
I'm happy that they aren't checking ID at the box office. I'm planning on treating my girlfriend and sister in law to Thunder tickets courtesy of myVegas and don't want any hassle.
I got tickets for LOVE at the Mirage and it would have been easy to pass them off or sell them to somebody else.
