Ah, thanks, I'll have to get in on that. Unfortunately I went and pre-ordered a UK copy because I thought we were getting a one-case version like the US one, so... well, I guess I'll have two copies
It's not the most special thing in the world. There's nothing more in that cardboard box and inside Bayo 1 case is literally just the game.
I don't think Bayo 2 had a manual either, just some generic black and white info sheet.
