Germany's week 49 top 100,Xenoblade Chronicles X charts high in its debut!(Likely 30k-40k, see the reasoning of the assumption in the op) Mario and Luigi paper Jam had a good opening too!

I don't think its that surprising of a number for XCX.

XCX has a built in player tracker in the very first boss that is a forced encounter, and the game keeps track of its kills (and how many people it has killed). It isn't perfectly synced to player count (obviously as not everyone is connected at all times or when they kill the boss) but its a very good approximation. It is also regional.

Both NA and EU have blown past Japan's opening week, and are well into the first triple digit individually.
