So, you're meant to download the card from here, give it to your friend. They then go to RS's fb page, and view the instructions to make a terrible looking origami cat. Which by the way, looks nothing like Bob.
I don't see the point. If you have a friend who plays RS (because those two go hand in hand), the promotion is unnecessary. If they don't play RS, they're going to visit the site looking forward to awesome origami instructions. They'll be disappointed.
In other news, Bethesda are releasing the tools they used to make Skyrim for free to the public in January, for modding purposes. Nice when the game's company does things just to be kind to it's players, not to force them into paying more.
