Compilation of Final Fantasy VII?

ok first of all before crisis and crisis core happen in events before final fantasy VII , Advent Children happens two years after the events of final fantasy VII and Dirge of Cerberus happens one year after Advent Children but they might be reversed because i haven't played or watched ether in months and as for last order i don't know i haven't heard of it yet.......Sephiroth RULEZ!!!!!!!!
