Other than casework, is there any difference between the regular TMGC+C and the Exmotchi (Exile edition of the TMGC+C)?
The reason I ask is that this morning I found a Exile password on a Japanese BBS. It works on my regular TMGC+C. (The password is listed here: http://tama-zone.com/index.php?showtopic=20439
The password gives you a package of letter seeds.
Which grows into a letter tree.
After harvesting, a letter appears in your Special items.
When you use it, the letter flies up off the screen.
And then soon afterwards, a random visitor from Exile arrives.
