Before Crisis and the Snowboarding game are both for Mobile phones.
I think BC might be out in America, not sure though.
Dirge of Cerberus is out in Japan, but nowhere else yet.
Crisis Core isn't out yet.

The only one of them that's been released in America is Advent Children, unless BC has been released.

The order of the games is

BC > CC > Last Order > FF7 > Advent Children > Dirge of Cerberus

At least, I think it is.
