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.
YMMV: All Yesterdays
Genius Bonus: The artwork contains a lot of paleoart references that aren't explicitly stated in the text. The scaly, shrink-wrapped face of the cat, for example, is a Take That to feathered dinosaurs commonly being portrayed with scaly heads, despite there being hardly any evidence to support this.
Sequelitis: All Your Yesterdays was significantly less well received than the original. This may have something to do with a large portion being contributions from non-experts.
