Oh man, I think I'm going to have to get a 3DS with Zelda. I haven't gamed on a handheld since the GBA but there's just too many great games on the 3DS and this deal will push me over the edge (as long as it comes to Australia too).

Because if you have owned a 3DS for so many years and don't own at least one of these games, you don't deserve it. I own three of the listed games.

...And Super Mario 3D Land.

I sort of with the promotion let you get any one game from the list if you already have a game on the list AND Super Mario 3D Land. I would have loved to have been able to nab A Link Between Worlds for free, but oh well. 

Great promotion, though it doesn't have much use to me.

Oh, btw., the second link in the OP is wrong (as it has the . at the end of the scentence as part of it). But thanks for showing me one of the most hilarious Error 404 pages I have ever seen.

It's called Club Nintendo. Only took me two consoles and about twelve games to get a Platinum Super Mario Galaxy soundtrack :P
