On that point, the jsondb api discussion said they could do Samegame 
highscores with their API too ;). So I'd like to add the further question: 
Where's the boundary between when you'd use Settings and when you'd use 
JsonDb? Some grey area, where either would work, might be inevitable but they 
need several clearly distinct usecases to make it worth adding both.
