Game Ads

Has anyone been seeing the ads for Burger King video games? I ran across this post which sorta explains a lot about it, but basically Burger King's putting out three Xbox360 games that you can buy for $3.99 each with the purchase of a value meal. I'm wondering how much the game feels like a game and how much it feels like an ad...it seems so strange to pay someone money so you can watch their advertisements. Are there other brands out there doing the same kind of thing? I've seen silly little online games that are advertisements, but nothing this elaborate. Or maybe I've been missing stuff--is this becoming a common thing now?
