Final Fantasy II is my least favorite. You can spend days trying to level it up but still not make a cure spell as well as other games. Final Fantasy VIII is so terrible to get when you draw from monsters. Still that game has summons. Final Fantasy XI takes too much MP to cast a lot. You need to knell and/or use expensive items to gain mp. However I am not a fan of Final Fantasy I and III when each level has an x amount of times you can cast.
