Anyway, I have a fun game for FE Fans and everybody else.

Using the Tactician Birthmonth and Blood Type(you can use either International or Japanese), determine your Affinity. If you don't know your Blood Type, use something like 1st Quarter, 2nd Quarter, 3rd Quarter and 4th Quarter or Fifths if you mix the NA Affinities with the JP Affinities. Ice and Anima are also treated as Water and Earth.
And if you want to really have fun, use the Tactician Birthmonth and Blood Type to give the Awakening and Fates characters Affinities using their Birthdays.
Edit: Oh, just to mention, mine would be Thunder.
