This quick read gives a good history of the aspects and how they have been tweaked to make the game better. It goes on to give very good advice about how to modify them for your particular game or group of players.

It's probably worth buying for the 99 cents since it does a good job of explaining existing approaches. However, if you're led by the description to believe that it has a large selection of alternative approaches, it doesn't really. It has lifted abilities from other game systems and done little more than list them as approaches with no real advice about how you'd implement it. For D20-like systems, the opening "You can easily take the six attributes [from d&d] and convert them over into approaches for FAE," is only followed up with a list of the attributes with a brief description and the instruction to, "rename Talents by calling them Feats." And that's about it.
