These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Sequelitis: Some people don't mind the limited differences between each sequel, and some think the series has gotten stale. This is especially evident in the reviews for New World, where the opinions are split between "great" and "too different."
