With Pandora's Tower out in Europe today, the so-called Operation Rainfall trilogy is complete. Register all three games — Pandora's Tower, Xenoblade Chronicles and The Last Story — in Club Nintendo and you could get a nice surprise.
Nintendo Lee (no relation) states Nintendo Europe is offering a commemorative coin collection to those who registered all three games. The coins bear their respective game's logo on one side and a symbol or icon on the reverse, and come in a special presentation case. It doesn't matter if you bought the limited edition or regular game either.
Just like the gold Wii Remote Plus that came with The Legend of Zelda: Skyward Sword, Nintendo would like you to know that "the Club Nintendo RPG Commemorative Coin Collection is gold-coloured only and does not contain any real gold."
We imagine these are limited edition so may want to type in those codes pretty quickly. Certainly better than a poke in the eye with a blunt stick, eh?
