Sorry if I post this in the wrong forum, I'm not really that experienced on this forum.

I recently received a japanese version of Sonic and the Secret Ring for Nintendo Wii. It's still sealed, but I think it's not the normal retail version. First of all, the game is in a see-through case, and Wii games normally come in a white box. Second, I can see the manual, and it seems to be only a few pages, like a brochure of some kind. I have been doing some research, but I can't seem to find any decent information on the net. I have read something about a trial of Sonic & the Secret Rings, available only in Japan. I also think the serial number on this game is different from the serial number of the retail Sonic game.

Does anybody know anything about this game, or the trial I was talking about? I'll try to post some pictures too, maybe someone here know anything. And, sorry again if I posted this on the wrong forum, please move it if so :-)
