Thanks guys!
The Japanese Wii game is Captain Rainbow (it's awesome and bizarre). God only knows why Galaxies has such a hideous spine but the game still rocks so it's all good.
Also, it's funny that you mention the picture frame idea BnM. Chessa and I planned to do just that, but couldn't find generic frames that fit any of the posters. Our only option were custom frames, which given the number of posters, was getting a bit pricey. I think it's still an idea we are going to keep in mind and if we ever see some that will work, we'll definitely be making the switch.
