I don't think that the depiction would interfere the message.
I think of it this way, facts itself don't have flavor, the
presentation of the facts sets its flavor. I also think that
if the fact itself is grim, a contrasting presentation could
have a balancing effect.
In that case, you use something that the player feels safe to
explore subjects that would be otherwise threatening to
explore.
In the concept of the Stone Age story, the safety zone is the
style of the pixel art and the familiar platformer gameplay.
The presentation could have taken a realistic approach using
realistic 3D models. But that would be the same reason that
people don't just pick up a history book and read it.
This is an webcomic about middle east conflict. It has the same
effect by using a zone of safety (for reader who are familiar
with that art style) to help the reader through a sequence of
historical development.
The differences between the stages:The plains has the biggest animals. However, unlike the professional predators
like the lions, hubby has no claws, no sharp teeth, and no speed to pursue an
animal. Even lions hunt in groups, there is no way hubby could score one of
those big animals home alone (or is there?)
>> Hubby throws pebble at Elephant.
>> Elephant is enraged.
>> Elephant stomps hubby. Hubby takes 2900 HP damage.
>> Hubby is defeated.
When the player tries to hunt an elepant the player could get a sequence of
events like above. That result occurs because the player is exploring, or
wrongly assumed wild lives relatively easy to defeat. This sets the paleolithic
mindset where wild lives are very dangerous, and human dominates nowhere.
It is a period when life is not safe and human is a species barely surviving,
(until...)
The canyons and mountains have different animals to give a different dynamic.
The canyons has small animals, it is safer but it is dry and has little food.
The player would play and discover which environment has the best chance
to get the most food home. The chapter ends with a fact reflecting the player's
encounter.
