Each version of Fire Emblem Fates does not have as much content as Awakening.

[Jranation]

Also want to note the blocks it takes:

FE:A - 8,579 blocks 

FE: Fates - 24,666 blocks

 

BUT!!!!!!!!!! According to Serenes Forest, Fates only use 12,239 blocks. The remaining ones could be related to the other Versions. 

Soooo this is another way to see which one has more "Content" without actually playing the game.
