Secrets and Treasures is real, I posted it up. Do you see Terraria in the WP region? 505 says it should be out Friday and the icon they posted on Twitter has the Xbox logo like it should be Live enabled.
I posted the X1 list first based on the list they posted on their website (with N/A in all the values), then when I found the 360 list I posted that and copied the values over. Wouldn't be surprised if there was a JP list for this game, it's called "Psycho Break" over there.
